Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...
Modeling in Therapy01:26

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
Participant Modeling
Participant modeling involves therapists demonstrating calm and effective behaviors in situations...
Generalized Anxiety Disorder01:30

Generalized Anxiety Disorder

Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...
Adrenal Gland Disorders01:27

Adrenal Gland Disorders

Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Summary

Attention deficit hyperactivity disorder (ADHD) affects adults, with symptoms often starting in childhood. Diagnosis requires careful patient history and symptom evaluation, as objective tests are unavailable.

Area of Science:

  • Neurobiology
  • Psychiatry

Background:

  • Attention deficit hyperactivity disorder (ADHD) is a neurobiological condition with symptoms persisting into adulthood.
  • Adult ADHD presents with unique manifestations and higher comorbidity rates compared to childhood.
  • Common adult symptoms include concentration difficulties, memory issues, disorganization, and impulsivity.

Purpose of the Study:

  • To highlight the diagnostic challenges and specific clinical manifestations of adult ADHD.
  • To emphasize the importance of comprehensive patient evaluation for accurate diagnosis.
  • To outline current treatment approaches for adult ADHD.

Main Methods:

  • Review of clinical manifestations and diagnostic criteria for adult ADHD.
  • Analysis of comorbidities associated with adult ADHD.

  • Evaluation of current pharmacological and psychosocial treatment strategies.

    • Main Results:

    • Adult ADHD is underdiagnosed due to historical focus on childhood cases.
    • Diagnosis relies on patient history, symptom presentation, and comorbidities, lacking objective biomedical tests.
    • Self-evaluation scales are crucial aids in the diagnostic process.

    Conclusions:

    • Adult ADHD requires specific diagnostic approaches distinct from childhood presentations.
    • Comprehensive patient records, including childhood history and comorbidities, are essential.
    • Integrated treatment involving psychopharmaceuticals (methylphenidate, atomoxetine) and behavioral therapies is recommended.
