Abstract

Insights

Minor physical anomalies (MPAs) may indicate abnormal brain development in affective disorders. Research suggests a stronger link in bipolar disorder than unipolar depression, though studies are limited.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Genetics

Background:

  • Minor physical anomalies (MPAs) are potential external markers of abnormal brain development.
  • Affective disorders, including bipolar disorder and unipolar major depression, may be associated with increased MPA prevalence.

Purpose of the Study:

  • To review the current knowledge on MPA prevalence in affective disorders.
  • To address controversies and inconsistencies in existing research.
  • To recommend future research directions.

Main Methods:

  • A comprehensive literature search was conducted using MEDLINE, PsycINFO, and Web of Science.
  • Publications focusing on the prevalence of MPAs in bipolar affective disorder and unipolar major depression were included.
  • Studies with varying patient numbers and sensitivity scales were evaluated.

Main Results:

  • 14 publications from 12 studies were identified.
  • Prevalence data for MPAs were analyzed across bipolar disorder, unipolar depression, and combined mood disorder groups.
  • Some studies combined data, limiting specific comparisons.

Conclusions:

  • Existing studies on MPA prevalence in affective disorders are limited by small sample sizes.
  • Aberrant neurodevelopment appears more probable in bipolar affective disorder than in unipolar major depression.
  • Further research is needed, particularly distinguishing between bipolar I and bipolar II disorders.

Introduction to Psychological Disorders

Abnormal behavior, often referred to as mental illness, results from changes in brain function that influence thought patterns, behaviors, and social interactions. Psychologists and psychiatrists typically assess abnormal behavior using three primary criteria: deviance, maladaptation, and personal distress, particularly when these traits persist over long periods.
Deviant Behavior
Deviance in behavior refers to actions or thought patterns that significantly diverge from societal norms or...
Depressive Disorders: Etiology01:27

Depressive Disorders: Etiology

Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...
Theoretical Approaches to Psychological Disorder01:29

Theoretical Approaches to Psychological Disorder

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...
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.

Role of Affect in Interpersonal Attraction01:24

Role of Affect in Interpersonal Attraction

Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior elicits...
The Influence of Affect on Cognition01:29

The Influence of Affect on Cognition

Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...
