Attention-Deficit/Hyperactivity Disorder

1.3K
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....

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

2.4K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

1.7K
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Biological Causes of Schizophrenia01:29

Biological Causes of Schizophrenia

1.0K
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...

Theoretical Approaches to Psychological Disorder

1.0K
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

Disorders of the Nervous Tissue

3.0K
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Area of Science:

  • Neuroscience
  • Psychiatry
  • Genetics

Background:

  • Increased prevalence of psychiatric and neurodevelopmental disorders necessitates a closer look at their clinical overlap.
  • Evolving diagnostic criteria impact the understanding and classification of these conditions.

Purpose of the Study:

  • To review the growing evidence of psychiatric comorbidities in neurodevelopmental disorders.
  • To examine the genetic underpinnings and shared features between distinct clinical conditions.
  • To challenge traditional boundaries of psychiatric disorders and the concept of comorbidity.

Main Methods:

  • Literature review of recent studies on psychiatric comorbidities.
  • Analysis of research on genetic overlap between disorders.
  • Examination of behavioral and psychiatric features in intellectual developmental disorders.

Main Results:

  • Significant psychiatric comorbidities are identified in autism and genetic syndromes.
  • A growing body of evidence points to shared genetic factors between previously separate disorders.
  • Behavioral and psychiatric symptoms are increasingly recognized in individuals with intellectual developmental disorders.

Conclusions:

  • Advances in understanding genetic links necessitate a re-evaluation of psychiatric disorder classifications.
  • The concept of comorbidity requires review in light of the interconnectedness of these conditions.
  • Redrawing diagnostic boundaries is essential for a more accurate clinical approach.
