  • Family Structure, Romantic Partnership, and Caregiver Status

Attention-Deficit/Hyperactivity Disorder (ADHD)

• Overview and Diagnostic Specifiers:

  • Attention-Deficit/Hyperactivity Disorder (ADHD) is categorized in the DSM-5 into three primary diagnostic specifiers:

  • Inattentive ADHD: Characterized primarily by difficulties in sustaining attention, focus, and organization, alongside high distractibility. Hyperactivity symptoms are typically absent.

  • Hyperactive-Impulsive ADHD: Characterized by excessive, disruptive physical behavior and severe impulse control deficits. Inattention and distractibility are rarely observed. This represents the least common presentation of ADHD.

  • Combined ADHD: Characterized by a combination of both inattentive and hyperactive-impulsive symptom clusters. This represents the most common presentation of ADHD.

• DSM-5 Diagnostic Criteria for Inattentive ADHD:

  • Requires the persistent presence of at least $6$ of the following symptoms for a duration of at least $6\,\text{months}$:

  • Difficulty paying close attention to details or making careless mistakes.

  • Difficulty sustaining attention in tasks or play activities.

  • Appearing not to listen when spoken to directly (mind seems in the clouds).

  • Failure to follow through on instructions and failure to finish duties or tasks.

  • Difficulty organizing tasks, activities, and managing time.

  • Avoidance, dislike, or reluctance to engage in tasks requiring sustained mental effort.

  • Frequent loss of items necessary for tasks or activities.

  • High susceptibility to distraction by extraneous stimuli or internal thoughts.

  • Frequent forgetfulness in daily activities.

• DSM-5 Diagnostic Criteria for Hyperactive-Impulsive ADHD:

  • Requires the persistent presence of at least $6$ of the following symptoms for a duration of at least $6\,\text{months}$:

  • Frequent fidgeting, tapping hands/feet, or squirming in seat.

  • Inability to remain seated in situations where sitting is expected (such as classroom or workplace environments).

  • Feelings of restlessness or inappropriate running/climbing.

  • Inability to engage quietly in leisure or play activities.

  • Talking excessively or blurting out thoughts without thinking.

  • Severe difficulty waiting for one's turn.

  • Frequent interrupting or intruding on others during conversations or activities.

• Etiology and Causes of ADHD:

  • Genetics: Plays a major underlying role in vulnerability, though definitive proof of a single congenital origin remains undetermined.

  • Environmental Toxin Exposure: In utero or early childhood exposure to environmental toxins increases risk.

  • Fetal and Pregnancy Health: Exposure to tobacco smoke or alcohol during gestation elevated disorder risk. A $2018$ study demonstrated significantly higher risk among children whose birthing parents were heavy smokers.

  • Traumatic Brain Injury (TBI): Brain damage resulting from early life trauma, physical head injury, or abnormal cerebral development.

  • Infectious Illnesses: CNS infections during childhood, specifically meningitis or encephalitis.

• Treatment Modalities for ADHD:

  • Behavioral Therapies:

  • Cognitive Behavioral Therapy (CBT): Assists individuals in managing specific real-life daily challenges (e.g., paying bills on time) and interpersonal situations (e.g., developing workplace assertiveness).

  • Psychoeducation:

  • Educates patients on the neurodevelopmental mechanisms of ADHD to clarify symptom origin and self-management.

  • Coaching and Skills Training:

  • Tailored coaching programs offered in-person, via phone, or through video call by certified specialists.

  • Pharmacotherapy:

  • Stimulants: Recognized as first-line pharmacotherapy due to high efficacy, rapid onset, and manageable safety profiles.

    • Methylphenidate Formulations: Ritalin, Concerta, Metadate, Methylin.

    • Amphetamine Formulations: Adderall, Dexedrine.

    • Adverse Effects: Tachycardia (fast heart rate), elevated blood pressure, mid-day appetite suppression, insomnia/sleep disruption, increased anxiety or irritability, mild abdominal pain, mild headache, and rarely motor tics.

  • Non-Stimulants: Prescribed when stimulants are ineffective, produce intolerable adverse effects, or are contraindicated by comorbid conditions (e.g., cardiovascular disease).

    • Atomoxetine (Strattera)

    • Guanfacine (Intuniv ER)

  • Antidepressants: Prescribed off-label when standard treatments are unsuitable.

    • Norepinephrine-Dopamine Reuptake Inhibitors (NDRIs): Bupropion

    • Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs): Venlafaxine

    • Tricyclic Antidepressants (TCAs): Desipramine, Imipramine

  • Neurostimulation Therapy:

  • Direct neurostimulation targeting brain regions displaying dysregulated or irregular electrical activity.

• ADHD Comorbidities:

  • ADHD frequently co-occurs with Major Depressive Disorder, Bipolar Disorder, Anxiety Disorders, Substance Use Disorders (SUD), Oppositional Defiant Disorder (ODD), and Conduct Disorder.

Oppositional Defiant Disorder (ODD) and Conduct Disorder

• Oppositional Defiant Disorder (ODD):

  • Definition: A childhood disorder defined by persistent anger, irritability, and defiance toward authority figures lasting at least $6\,\text{months}$.

  • Diagnostic Criteria: Must display at least $4$ symptoms across three categories for at least $6\,\text{months}$:

  • Angry/Irritable Mood: Frequently loses temper, easily touchy/annoyed, often angry and resentful.

  • Argumentative/Defiant Behavior: Frequently argues with adults or authority figures, actively defies or refuses compliance with requests/rules.

  • Vindictiveness: Has been spiteful or vindictive at least $2\,\text{times}$ within the preceding $6\,\text{months}$, deliberately annoys others, or shifts blame for mistakes onto others.

  • Treatment: Dual-branch approach utilizing psychotherapy and prescribed pharmacotherapy.

• Conduct Disorder:

  • Definition: Characterized by persistent, severe destructive, unruly, or violent behaviors, a general disregard for others' rights, and reckless boundary violations.

  • Age-of-Onset Subtypes:

  • Unspecified Onset: Age of symptom onset cannot be determined.

  • Childhood Onset: Diagnostic signs present prior to age $10\,\text{years}$.

  • Adolescent Onset: Diagnostic signs emerge during adolescence.

  • Etiology: The underlying biological and environmental causes remain unknown.

• Diagnostic Interrelationship:

  • Children diagnosed with ADHD show heightened susceptibility to developing ODD or Conduct Disorder.

  • Exclusionary Rule: A patient cannot receive simultaneous diagnoses for both ODD and Conduct Disorder because ODD functions as a direct developmental precursor to Conduct Disorder.

Autism Spectrum Disorder (ASD)

• Core Definition and Continuum:

  • A neurodevelopmental disorder altering social interaction, communication modalities, and behavioral patterns. Needs range along a continuous spectrum from low to high support requirement.

• Clinical Manifestations and Behavioral Signs:
