    • Alcohol is primarily recreational rather than medicinal, easily absorbed from the GI tract, and metabolized in the stomach and liver
    • Genetics play a role in alcohol metabolism, with different alleles affecting alcohol sensitivity and risk of alcoholism
    • Alcohol is a general CNS depressant and not a stimulant, affecting GABA and NMDA receptors
    • Alcohol withdrawal can lead to severe symptoms such as delirium tremens, extreme anxiety, and panic attacks
    • Cannabinoids are used more widely than all other classes of illicit drugs combined
    • Cannabis can be consumed through various routes, with psychoactive effects and potential side effects
    • Withdrawal from marijuana can lead to symptoms such as irritability, depressed mood, and lack of appetite
    • Opioids, such as morphine and fentanyl, work on the body's own opioid system and can lead to euphoria, drowsiness, and slowed breathing

    • Basal Ganglia, including the Caudate nucleus and putamen, are important for action selection and motor control, and are highly dopaminergic.
    • Nucleus accumbens/ventral striatum is heavily implicated in reward processing, showing greater activation in adolescents when engaging in tasks with peers, making activities more rewarding.
    • Ventral striatum is associated with rewards and early stages of learning, while dorsal striatum is associated with learning habits and skills.
    • A new hypothesis for anorexia suggests that individuals learn dieting behaviors in adolescence and that these behaviors become ingrained habits associated with functional abnormalities in the striatum.

    ADHD and Autism Spectrum Disorder: Clinical and Biological Insights

    • Girls with ADHD may be less over-active and may not be diagnosed, but around 50% experience problems as adults
    • ADHD is highly comorbid, with 80% of children having oppositional defiant disorder (ODD) and 90% of adults having mood disorders
    • ADHD is associated with neural changes in brain structure and function, including smaller brain volume and altered development in frontal cortex and basal ganglia
    • Methylphenidate (Ritalin) is a commonly used ADHD medication that inhibits monoamine reuptake and affects dopamine transporter and receptor genes
    • Stimulant medications like Ritalin are effective for 70% of ADHD patients, but may have side effects like anxiety and sleeplessness
    • Behavioral treatments for ADHD include reinforcement programs, parent training, and social skills training to improve behavior and self-esteem
    • Combined treatments, especially for cases with comorbid problems, are recommended for ADHD
    • Autism Spectrum Disorder (ASD) is characterized by persistent deficits in social communication and interaction, and restricted repetitive patterns of behavior
    • The DSM-V specifies three levels of autism to include more spectrum-based approaches, each with varying degrees of support required
    • ASD presentation is highly variable, with some individuals having very limited social interactions and others being high functioning
    • Genetic factors, gene-environment interactions, and prenatal/perinatal factors contribute to the etiology and pathogenesis of ASD
    • Known genetic mutations, polygenetic heritability, and prenatal/perinatal factors are associated with ASD, while vaccines are not a causative factor

    Neurodevelopment and Development Disorders

    • The basic structure of the brain is laid out during prenatal development and is similar to that of an adult in most major structural ways.
    • However, it takes years of fine-tuning before the brain functions like an adult and has adult-like microstructure.
    • Synaptogenesis is a rapid period of synapse formation which contributes to the growth of grey matter in the brain.
    • Synaptic production and pruning correspond with overall brain activity, with young children's brains working harder and less efficiently than adults'.
    • Synapse rearrangement occurs as active synapses likely take up neurotrophic factor to maintain stability, while inactive synapses get too little neurotrophic factor to remain stable.
    • Even during infancy, resting state brain networks similar to those observed in adults are detectable, and the development of these networks follows certain principles.
    • Plasticity plays a vital role in the development of synapses, with the selection of which synapses are strengthened and eliminated largely due to the environment.
    • The effects of experience on the brain are evident from a study on rats raised in different environments, showing that environmental factors impact brain development.
    • Brain maturation across childhood occurs at different times in different brain regions, leading to varying periods of vulnerability and resilience.
    • Critical and sensitive periods in brain development have distinct characteristics, with critical periods being abruptly defined and sensitive periods gradually defined.
    • ADHD is characterized by persistent patterns of inattention and/or hyperactivity-impulsivity that interfere with function or development, with specific criteria for diagnosis.
    • The prevalence of ADHD is 5% among school-aged children, with onset typically at age 3 or 4 and a higher prevalence in boys compared to girls.

    Understanding Eating Disorders and Treatment Approaches

    • Social media content on food/health includes both positive and negative discussions, which can potentially promote positive dietary behavior.
    • Family influences on eating disorders include specific characteristics of mothers of affected girls and the impact of family dynamics.
    • Psychological dimensions of eating disorders encompass factors such as low self-confidence, perfectionistic attitudes, and distorted body image.
    • Triggers for eating disorders range from puberty onset to medical illness causing weight loss and attempts to improve athletic performance.
    • Genetic influences are evident in the familial tendency for eating disorders, with relatives of patients being 4-5 times more likely to develop the disorder themselves.
    • Developmental considerations highlight the onset of eating disorders in adolescence and the influence of social ideals on body image concerns.
    • Adolescence is a period of high susceptibility to peer influence, affecting reward processing in the brain's ventral striatum.
    • The basal ganglia, including the caudate nucleus and putamen, are crucial for action selection and motor control, with implications for disorders like schizophrenia and substance abuse.
    • The nucleus accumbens in the ventral striatum is heavily implicated in reward processing and shows greater activation in adolescents during rewarding tasks with peers.
    • The ventral striatum is associated with early stages of learning and reinforcement, while the dorsal striatum is linked to habit and skill learning.
    • A new hypothesis suggests that individuals with anorexia learn dieting behavior in adolescence, leading to ingrained habits associated with functional abnormalities in the striatum.
    • Treatment approaches for eating disorders include cognitive-behavior therapy and interpersonal psychotherapy for bulimia, while anorexia may require weight restoration and psychological interventions.
