Introduction to Psychological Disorders01:19

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...
Behavior Modification01:21

Behavior Modification

Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.
A real-world application of operant conditioning principles is applied...
Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
What is Behavior?00:54

What is Behavior?

Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.
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.
Diagnostic Criteria and...
Deviation from Ideal Behaviour01:23

Deviation from Ideal Behaviour

Real gases do not perfectly obey the ideal gas laws, especially at high pressures and low temperatures or when they are about to condense to a liquid. These deviations occur due to intermolecular forces between gas molecules. Repulsive forces aid expansion and are significant when molecules are very close together, typically at high pressure. Attractive forces assist compression and have a longer range, being effective over several molecular diameters. They become significant when molecules are...

Summary

Japan

Area of Science:

  • Gerontology
  • Emergency Medicine
  • Neurology

Context:

  • Japan's rapidly aging population presents unique challenges for healthcare.
  • Increased elderly emergency room visits require specialized diagnostic approaches.
  • Vague symptoms in older adults can mask severe underlying conditions.

Purpose:

  • To highlight the importance of recognizing behavioral abnormalities in elderly emergency room patients.
  • To emphasize the critical role of assessing consciousness disturbance in this demographic.
  • To describe emergency conditions presenting with behavioral changes in the elderly.

Summary:

  • Behavioral abnormalities in elderly emergency patients necessitate immediate assessment for disturbed consciousness.
  • Prompt identification and treatment of consciousness disturbance are crucial for managing severe conditions.

  • This report details emergency diseases manifesting as behavioral changes in older adults.

    • Impact:

    • Improved diagnostic accuracy for elderly patients with non-specific symptoms.
    • Enhanced emergency medical treatment protocols for geriatric behavioral emergencies.
    • Reduced risk of misdiagnosis and delayed treatment for critical conditions in the aging population.
