September 08, 2025 #38: Deep Sleep - why is it important and how can you boost it?
Deep sleep, also called slow-wave sleep, is the most restorative stage of the sleep cycle. During this phase, brain activity slows into synchronized, high-amplitude waves, allowing the body and mind to recover. Research shows that deep sleep is essential for mental clarity, memory consolidation, and learning: it helps the brain organize and store new information, clear metabolic waste, and reset neural circuits for optimal performance the next day. Studies also link higher quality deep sleep to improved focus, problem-solving, and emotional regulation. In short, deep sleep is the foundation for both cognitive resilience and long-term brain health.
Join me today in my discussion with Dr. Paul Muchowski from Defined Sleep, as he discusses research on deep sleep.

February 03, 2024 #37: ADHD: What is it? How is it diagnosed?
Attention Deficit Hyperactivity Disorder (ADHD) is:
A neurobiological disorder that presents in childhood with the core symptoms of inattention, hyperactivity, and/or impulse control problems.
The symptoms are present across multiple domains: social, domestic, academic, as well as cognitive and behavioral functioning.
Pathogenesis: not very well understood. Deficits are in area of:
- Frontal-subcortical areas dealing with executive function
- May also involve working memory impairments and information processing speed deficits
Neuroimaging shows structural brain abnormalities in ADHD:
- smaller volumes of frontal cortex, cerebellum, and subcortical structures.
- Abnormalities in the prefrontal and parietal circuits.
Early studies suggest that the subcortical abnormalities noted in childhood normalize in adulthood but that cortical abnormalities may last.
Studies suggest hypoactivity of dopamine and norepinephrine in the frontal-subcortical circuits contributes to presentation.
Genetically, risk of ADHD in parents or siblings is increased 2-8x and twin studies show heritability of 76%.
ADHD is a syndrome with two core symptom categories: hyperactivity/impulsivity and inattention.
One potential intervention for attention problems is to get rid of digital distractions. I use Zenze - a robust app-blocking app which allows you to block any apps or content you'd like according to whatever schedule you'd like. You can block social media apps during work hours or video streaming at night - whatever you need. Personally, I use it to block all social media/video/entertainment apps at nighttime to prevent bedtime binging.

August 24, 2021 #32: Schizophrenia: Is it related to marijuana? What is schizophrenia? How is it treated?
#Schizophrenia is a very misunderstood mental illness. It is not "split personality" (or dissociative identity disorder), but rather a chronic, long-standing (6+ month) pattern of delusions, hallucinations, disorganized behavior, etc. There are #genetic risks to developing the illness and #cannabis likely increases risk. According to the "Dunedin" study, Archives of General Psychiatry 2000, those who used cannabis at age 15 were 4x more likely to develop schizophrenia or schizophreniform disorder.
