ADHD — The Rundown

Attention deficit hyperactivity disorder (ADHD) is characterized by executive dysfunction and emotional dysregulation.

Executive dysfunction: impaired cognitive control over goal-oriented behavior. It often presents as difficulty defining goals, initiating tasks, suppressing impulses, regulating attention, using working memory, and multitasking.

Emotional dysregulation: difficulty managing emotions, resulting in intense or sustained emotional reactions

Impacts

ADHD has effects on personal, social, academic, and professional life. Problems with impulse control can lead to addiction and social conflicts, and executive dysfunction as a whole causes problems maintaining schoolwork and professional obligations.

Over ¼ of people living in detention centers meet criteria for ADHD, while ADHD is only present in around 4% of adults in the general population.

ADHD is also associated with a lower life expectancy (by about 13 years).

Around 40% of Americans with ADHD were smokers in 2008 as compared to 20% of the general population in 2009, which is comparable to other psychiatric disorders.

ADHD is also associated with a greater risk for suicidal ideation, behavior, and attempts. Roughly ¼ of suicidal children under 12 have ADHD, and ADHD adolescents are more likely to also have issues with anxiety, major depressive episodes, chronic depression (dysthemia), and addiction. On it's own, ADHD is associated with 1.5× the amount of suicidal ideation in the general population, while ADHD alongside comorbid conditions has 4–12× the amount.

Causes

ADHD is associated with various structural differences in the brain, particularly in the prefrontal cortex (PFC). The PFC is responsible for executive functioning, and it is very sensitive to neurochemical imbalances. ADHD is strongly believed to result from lowered dopamine and norepinephrine activity, weakening the PFC and resulting in executive dysfunction. Some studies have also shown that children with ADHD have reduced grey matter in the prefrontal cortex, although I was not able to access this book due to the paywall.

Treatment

The most common and effective treatments for ADHD are stimulant medications, of which there are many types. Some of the most common options involve methylphenidate (branded as Ritalin or Concerta), and amphetamines (used in Adderall, Mydayis, Dexedrine, and Vyvanse).

Methylphenidate acts as a norepinephrine and dopamine reuptake inhibitor (NDRI), meaning it slows the reabsorption of those neurochemicals. Amphetamines work by increasing catecholamine activity. Catecholamines are a group of neurotransmitters often associated with the fight or flight response, including dopamine, norepinephrine, and adrenaline. Catecholamines are associated not only with anxiety, restlessness, and fear, but also with focus, awareness, wakefulness, and reflexes, as well as a variety of physical effects.

Problem-Solving and Decision-Making: A Process-Driven Approach to Mastery

Since when I was a kid, think 5 years old, I discovered that I excelled in both problem-solving and decision-making. Later in life, I became aware that they also are fundamental to our human experience, shaping our lives, careers, and relationships.

Mastering Dopamine: Science-Backed Strategies to Control Cravings, Boost Motivation, and Achieve Balance

Book pdf

Meta Description: Discover how dopamine influences motivation, pleasure, and behavior. Learn science-backed strategies to manage dopamine levels for better self-control and emotional balance. _______________________________

IntroductionDopamine, a vital neurotransmitter in the brain, plays a central role in motivation, pleasure, and behavioral reinforcement. Often dubbed the “feel-good” chemical, dopamine is linked to rewarding experiences that drive us to repeat specific actions. However, managing dopamine effectively is key to balancing motivation and avoiding impulsive behaviors. This article explores the science of dopamine and actionable strategies to harness its power. The Role of Dopamine in Motivation and Behavior1. Nucleus Accumbens: The Motivation Hub The nucleus accumbens, a brain region rich in dopamine receptors, generates motivation by associating actions with pleasure. When dopamine is released during rewarding activities—like eating or achieving a goal—it reinforces the behavior, making us more likely to repeat it. 2. Why Direct Control Over Dopamine Is Impossible Dopamine circuits drive desires and impulses, meaning we can’t “force” ourselves to feel motivated. Instead of battling cravings directly, focus on influencing other brain regions to regulate dopamine-driven urges. Key Strategies for Managing Dopamine1. Avoid Dopamine Depletion Early in the Day Starting your day with highly stimulating activities (e.g., social media, gaming) can drain dopamine reserves, making low-reward tasks (like work or study) feel unbearable. Prioritize meaningful tasks first to maintain steady dopamine levels. 2. Tackle Negative Emotions to Reduce Cravings Negative emotions like stress or sadness heighten sensitivity to dopamine signals. This is because dopamine temporarily suppresses discomfort, driving cravings for quick fixes. Techniques like therapy, journaling, or mindful walking can process emotions and reduce impulsive behavior. 3. Rewire Value Assessments with the Prefrontal Cortex The prefrontal cortex (PFC) evaluates long-term value. For example, choosing video games over studying reflects the subconscious assigning higher value to instant gratification. To shift this: - “Play the Tape to the End”: Write down the consequences of actions (e.g., procrastination) to consciously reassess their true cost. - Conscious Revaluation: Repeatedly reframe goals (e.g., “Studying leads to career growth”) to align subconscious priorities. 4. Leverage Novelty via the Hippocampus The hippocampus, involved in memory and novelty, boosts motivation when tasks feel stale. Add new elements to routines—like studying in a café or gamifying chores—to trigger fresh dopamine release. 5. Use Pain Strategically with the Opioid System Moderate discomfort (e.g., exercise, cold showers) activates the brain’s opioid system, which interacts with dopamine to enhance pleasure from accomplishments. Embrace manageable challenges to build resilience. -Why Dopamine Isn’t the EnemyDopamine isn’t inherently harmful—it’s essential for learning, growth, and persistence. The key lies in maintaining “dopamine reserves” for sustained effort. High baseline dopamine levels make it easier to derive satisfaction from low-reward tasks, fostering discipline over time. Practical Takeaways for Better Self-Control- Process emotions daily through meditation, journaling, or therapy. - Design your environment to minimize temptations during low-dopamine periods. - Reframe tasks by linking them to long-term rewards (e.g., “This workout builds future health”). - Embrace novelty and mild discomfort to strengthen motivation circuits. ConclusionDopamine drives our most fundamental behaviors, from chasing goals to seeking joy. By understanding its interplay with brain regions like the nucleus accumbens, prefrontal cortex, and hippocampus, we can adopt strategies to manage cravings, boost productivity, and achieve emotional balance. Start by addressing negative emotions, reassessing subconscious values, and embracing intentional challenges—all while respecting dopamine’s power as a catalyst for growth.

everything is wired - about dreaming

What do our dreams actually say about us? Do they have meaning or hidden messages?

I'm sure you have had a rather questionable dream one night and spent the morning with similar questions.

To really understand dreams and what they mean, I dug deep and i'm ready to give you the shortest of summaries.

I know every person has different opinions about where dreams come from and what they mean or even if they mean anything at all.

So, in my digging, i've assembled all sorts of information.

To put it simply, our brain doesn't rest when we do. Once we fall asleep, our brain finally gets to work without our silly little thoughts interfering.

This process is called Memory Consolidation.

Dreams are believed to contribute to the consolidation or memories, organizing and storing information acquired during wakefulness.

- Think of it as a shopping Haul. You've been out all day, shopping god knows what (for god knows how much) and then, once you get back home you unpack everything you've bought, take off the tags and store it somewhere in the depths of your (probably already overflowing) closet.-

Essentially, our brain is having a mega haul with all the experiences since the last time you slept. And with that, when it's deciding what goes from short to long term memory, it also pulls out other stuff, older stuff, older memories and maybe even old dreams that were so memorable that you brain decided, once you rest, to include it in your long term closet haul.

So now, at night, while you entered REM sleep, your brain is sorting through the meals you've had, the people you saw, the names you read on your phone or on a billboard, the colors of the city, the background music at the cafe and everything else you've absorbed, you begin to dream.

So, now you might ask: Why, when my brain is sorting through my very real daily experiences, do i sometimes dream about the most illogical and crazy things that makes absolutely zero sense?

Well, i told you i dug deep, so bear with me:

The Prefrontal Cortex, associated with decision making and logical thinking, shows reduced activity during dreaming, which might explain the illogical nature of (some) dreams.

So last night, when i dreamt about DNA reconstructing glasses that you pull over the back of your head (I wish i were kidding), it wasn't me going mental, it was just about Frontal Lobe Inactivity. Well, maybe both.

From inactivity to above average activity: Your Limbic System, responsible for emotions (and the reason why you might miss your silly ex) is highly active when dreaming, influencing the emotional content of dreams. Some people wake up after a dream and can't shake off the way it made them feel for the whole day.

Studies have shown that there is a small percentage of women who have dreamt of being pregnant -but then waking up only to find out that there is no baby- and felt extremely abandoned and depressed the following day; mourning for a baby that was never real.

So with that being said, yes, dreams aren't real, but then again, what are they, if not real?

You see them, you hear them, you feel them, sometimes even after waking up, so just because it only happened in your head, doesn't mean it's not real at all.

My DNA reconstructing glasses are definitely not in store yet, but as they lived in my brain, they are a part of reality.

So, if i haven't bored you yet, here come the answers to the questions i've asked.

This is what dreams are, what they do:

Reflection of Emotions: Dreams often reflect our emotional state and unresolved feelings.

Subconscious Desires and Fears: They may reveal hidden desires, fears, or concerns stored in the subconscious.

Problem-Solving: Dreams can aid problem-solving by processing information and experiences.

Symbolic Language: Dreams use symbolic language, requiring interpretation to understand their meaning.

Memory Consolidation: They may assist in consolidating and organizing memories from the day.

Creative Inspiration: Dreams can inspire creativity and provide unique insights.

Mind Processing: Dream content may represent the brain's way of processing daily experiences and emotions.

What I'm trying to say is: Do not push your dreams aside with a simple: "It's just a dream, it doesn't mean anything"

It might not mean "text your ex" or "find out if you can actually fly" but it means something.

While at times the meaning is abundantly clear, some dreams leave us with wonder and confusion.

I say, observe your dreams and thought and see if there is a pattern, a motive.

And buy my DNA glasses!

funny how i haven’t been on the general social media in a week and i feel like my prefrontal cortex got breath of fresh air

[rococo444]

just hangin on until i turn 25 and i can finally allow myself to make an Actual Decision with my brand new fully developed prefrontal cortex decision maker turbo 2000

[tk-n-la]

Nicely sums up why I hate it when a news report starts with "Researchers say..."

The whole "the brain isn't fully mature until age 25" bit is actually a fairly impressive bit of psuedoscience for how incredibly stupid the way it misinterprets the data it's based on is.

Okay, so: there's a part of the human brain called the "prefrontal cortex" which is, among other things, responsible for executive function and impulse control. Like most parts of the brain, it undergoes active "rewiring" over time (i.e., pruning unused neural connections and establishing new ones), and in the case of the prefrontal cortex in particular, this rewiring sharply accelerates during puberty.

Because the pace of rewiring in the prefrontal cortex is linked to specific developmental milestones, it was hypothesised that it would slow down and eventually stop in adulthood. However, the process can't directly be observed; the only way to tell how much neural rewiring is taking place in a particular part of the brain is to compare multiple brain scans of the same individual performed over a period of time.

Thus, something called a "longitudinal study" was commissioned: the same individuals would undergo regular brain scans over a period of mayn years, beginning in early childhood, so that their prefrontal development could accurately be tracked.

The longitudinal study was originally planned to follow its subjects up to age 21. However, when the predicted cessation of prefrontal rewiring was not observed by age 21, additional funding was obtained, and the study period was extended to age 25. The predicted cessation of prefrontal development wasn't observed by age 25, either, at which point the study was terminated.

When the mainstream press got hold of these results, the conclusion that prefrontal rewiring continues at least until age 25 was reported as prefrontal development finishing at age 25. Critically, this is the exact opposite of what the study actually concluded. The study was unable to identify a stopping point for prefrontal development because no such stopping point was observed for any subject during the study period. The only significance of the age 25 is that no subjects were tracked beyond this age because the study ran out of funding!

It gets me when people try to argue against the neuroscience-proves-everybody-under-25-is-a-child talking point by claiming that it's merely an average, or that prefrontal development doesn't tell the whole story. Like, no, it's not an average – it's just bullshit. There's no evidence that the cited phenomenon exists at all. If there is an age where prefrontal rewiring levels off and stops (and it's not clear that there is), we don't know what age that is; we merely know that it must be older than 25.

Does anyone else ever just get overwhelmed by how much they love the people in their lives?

Like your just sitting and then one minute your brain just flashbangs you with like your family and friends and you just feel like

“Hahahahhahaha what the fuck I love these people so much and I don’t know what I would do without them? 🥲😭”

Is this my prefrontal cortex developing?

Pine trees are resilient. They don’t have to be, but they are. Nature designed plants to be able to grow back… are humans the same way? After a forest fire do we continue to grow and change like an ecosystem or do we die off like the leaves in fall to grow back the same in the spring?

Understanding Anxious Attachment Style Through a Neuroscience Lens

Key Takeaways

Anxious attachment often stems from inconsistent caregiving during early childhood, leading to a heightened need for reassurance in relationships.

Neuroscience reveals that brain structures like the amygdala, prefrontal cortex, and hippocampus play crucial roles in the development of anxious attachment.

People with anxious attachment may struggle with trust and communication, affecting relationship stability.

Cognitive behavioral strategies and mindfulness can help manage anxious attachment tendencies.

Understanding and addressing anxious attachment can lead to healthier, more secure relationships.

The Neuroscience of Anxious Attachment

Anxious attachment is a fascinating area of study within both psychology and neuroscience. It describes a pattern of attachment behavior characterized by a deep-seated fear of abandonment and a constant need for reassurance from partners. To truly grasp why this happens, we need to delve into the neuroscience behind it.

Attachment styles are shaped by our early interactions with caregivers. When these interactions are inconsistent or unpredictable, they can lead to an anxious attachment style. This inconsistency triggers a heightened sensitivity to potential rejection or abandonment, which is deeply embedded in our brain's functioning.

Our brain plays a pivotal role in how attachment styles manifest. Various brain structures influence our emotions and how we react to attachment-related stimuli. Understanding these structures provides a clearer picture of why some people develop anxious attachment styles and how they can affect adult relationships.

Anxious Attachment Explained

At its core, anxious attachment is all about insecurity. People with this attachment style often worry excessively about their partner's love and commitment. They may constantly seek validation and fear that their partner will leave them. This can lead to behaviors such as clinging, jealousy, or even controlling tendencies.

These behaviors are not just random; they stem from a deep-seated need to feel secure and loved. The irony is that the very actions taken to seek reassurance often push partners away, creating a self-fulfilling prophecy of rejection and abandonment.

The Role of Early Childhood Experiences

Early childhood experiences are fundamental in shaping our attachment styles. When a child receives inconsistent care—sometimes attentive, other times neglectful—they may develop an anxious attachment style. This inconsistency creates uncertainty in the child's mind about whether their needs will be met.

For example, if a caregiver responds to a child's cries with comfort one day but ignores them the next, the child learns that their needs are not reliably met. This unpredictability fosters anxiety about whether they are worthy of love and care, leading to a constant search for reassurance as they grow older.

How Anxious Attachment Develops in the Brain

The development of anxious attachment in the brain is a complex process involving various neural circuits. The brain's fear and reward systems play significant roles in this development. When a child experiences inconsistent caregiving, their brain's fear circuitry becomes more active, heightening their sensitivity to potential threats, such as rejection or abandonment.

Moreover, the brain's reward system is also affected. When a caregiver provides comfort, the brain releases feel-good chemicals like dopamine, reinforcing the child's need for reassurance. However, the unpredictability of this comfort creates a cycle of anxiety and reward-seeking behavior.

As these neural pathways become ingrained, they influence how individuals perceive and react to attachment-related situations throughout their lives. This is why anxious attachment can persist into adulthood, affecting relationships and emotional well-being.

Brain Structures Influencing Anxious Attachment

Understanding the specific brain structures involved in anxious attachment can provide valuable insights into how this attachment style develops and manifests.

The Amygdala's Role in Anxiety

The amygdala is a key player in the brain's emotional processing, particularly in fear and anxiety responses. In individuals with anxious attachment, the amygdala is often more active, making them more sensitive to perceived threats in relationships. This heightened activity can lead to overreactions to minor conflicts or misunderstandings, as the brain interprets these situations as potential signs of abandonment.

Impact of the Prefrontal Cortex

The prefrontal cortex is responsible for higher-order thinking, such as decision-making and impulse control. In people with anxious attachment, the prefrontal cortex may struggle to regulate the emotional responses triggered by the amygdala. This can result in difficulty managing emotions and impulsive behaviors in relationships, as the logical part of the brain is overpowered by emotional reactions.

Hippocampus and Memory of Attachment

The hippocampus is crucial for memory formation and recall. In the context of anxious attachment, it helps store and retrieve memories of past attachment experiences. When a person with anxious attachment encounters a situation reminiscent of past rejection or inconsistency, the hippocampus retrieves these memories, reinforcing their fear and anxiety. This cycle perpetuates the anxious attachment style, as the brain continuously revisits past experiences to inform current behavior.

Effects of Anxious Attachment on Relationships

Anxious attachment can significantly impact the dynamics of a relationship. Those with this attachment style often experience heightened emotional responses, which can lead to misunderstandings and conflicts. Because of their constant need for reassurance, partners may feel overwhelmed or suffocated, leading to further tension and dissatisfaction.

Moreover, the fear of abandonment can result in a partner's actions being misinterpreted as signs of impending rejection. This can create a cycle where the anxious partner's behaviors inadvertently push their partner away, reinforcing their fears and insecurities.

Communication Challenges

Effective communication is the cornerstone of healthy relationships. However, for those with anxious attachment, communication can become a significant challenge. Their fear of rejection may lead to indirect communication or reluctance to express needs and desires openly.

For instance, an anxious partner might not express their feelings directly but instead drop hints or become passive-aggressive when their needs are unmet. This indirect communication style can confuse their partner, leading to misunderstandings and unresolved issues.

Trust and Relationship Stability

Trust is another area where anxious attachment can cause difficulties. The constant fear of abandonment can make it hard for individuals to fully trust their partners, even when there is no reason to doubt them. This lack of trust can manifest as jealousy, possessiveness, or constant questioning of the partner's actions and intentions.

Emotional Dependency and Conflict

High emotional dependency on partners for self-worth and validation.

Frequent conflicts due to perceived lack of attention or affection.

Difficulty in managing emotions, leading to outbursts or withdrawal.

Emotional dependency is a hallmark of anxious attachment. Individuals may rely heavily on their partners for validation and self-worth, placing undue pressure on the relationship. This dependency can lead to frequent conflicts, especially if the partner cannot meet these high emotional demands.

Moreover, the inability to manage emotions effectively can lead to either emotional outbursts or withdrawal. These extreme reactions can strain the relationship, making it challenging to maintain stability and harmony.

Addressing these issues requires both partners to work together to create a supportive and understanding environment. Open communication, patience, and empathy are essential in managing the challenges posed by anxious attachment.

Managing Anxious Attachment

While anxious attachment can pose challenges, it is not insurmountable. With the right strategies and support, individuals can learn to manage their attachment style and foster healthier relationships.

Understanding the underlying causes of anxious attachment is the first step. Recognizing that these behaviors stem from early experiences and brain wiring can help individuals approach the issue with compassion and a willingness to change.

Cognitive Behavioral Strategies

Cognitive behavioral strategies can be highly effective in managing anxious attachment. These strategies focus on identifying and challenging negative thought patterns that contribute to anxiety and insecurity. By reframing these thoughts, individuals can develop healthier beliefs about themselves and their relationships.

Mindfulness and Emotion Regulation

Mindfulness practices can also play a crucial role in managing anxious attachment. By cultivating present-moment awareness, individuals can learn to observe their thoughts and emotions without judgment. This awareness can help them respond to situations more calmly and rationally, reducing the likelihood of emotional outbursts.

Emotion regulation techniques, such as deep breathing or progressive muscle relaxation, can also help individuals manage their anxiety and emotional responses. These techniques provide tools to calm the nervous system and regain control over intense emotions.

Seeking Professional Help

For many, seeking professional help is a valuable step in managing anxious attachment. Therapists trained in attachment theory can provide insights and strategies tailored to an individual's needs. Therapy offers a safe space to explore past experiences, understand current behaviors, and develop new ways of relating to others.

"Therapy helped me understand my anxious attachment and gave me tools to communicate more effectively with my partner. It's been a game-changer for our relationship." – A real testimonial from a client who worked through their attachment issues in therapy.

In therapy, individuals can also work on building self-esteem and developing a more secure attachment style. This process takes time and effort, but with commitment and support, it is possible to move towards healthier, more fulfilling relationships.

Conclusion: Moving Towards Secure Attachment

Ultimately, the goal is to move towards a secure attachment style, where individuals feel confident in their relationships and are able to express their needs openly and directly. Building healthy relationship patterns requires self-reflection, patience, and a willingness to grow.

It's important to remember that change is possible, and with the right support and strategies, individuals can overcome the challenges of anxious attachment and build lasting, meaningful connections. For more insights, consider exploring this free presentation on relationship dynamics.

Building Healthy Relationship Patterns

Creating healthy relationship patterns starts with self-awareness and a commitment to change. It's essential to recognize how anxious attachment influences your interactions and be willing to adopt new strategies. Begin by fostering open and honest communication with your partner. Express your needs clearly and listen actively to theirs. This mutual understanding can lay the foundation for a more secure attachment.

Additionally, work on building trust by setting realistic expectations and being consistent in your actions. Consistency helps reassure both partners and builds a sense of reliability and safety within the relationship. Over time, these practices can transform the dynamics of your relationship, moving it towards greater security and fulfillment.

Importance of Self-Reflection and Growth

Self-reflection is a powerful tool in the journey towards overcoming anxious attachment. By taking the time to examine your thoughts, feelings, and behaviors, you can gain insights into the root causes of your attachment style. Consider journaling your experiences and emotions to track patterns and progress over time.

Growth requires patience and self-compassion. Recognize that change doesn't happen overnight and that setbacks are a natural part of the process. Celebrate small victories and learn from challenges. Remember, the goal is not perfection but progress. By embracing a growth mindset, you can cultivate a healthier relationship with yourself and others.
