Positive Symptoms of Schizophrenia: Hallucinations and Delusions01:30

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

958
Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes...

Narcolepsy01:07

Narcolepsy

721
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.

Panic Disorder01:27

Panic Disorder

1.0K
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

2.3K
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Mania and Antimanic Drugs: Overview

741
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as...

Bipolar Disorder01:30

Bipolar Disorder

1.3K
Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

Area of Science:

  • Psychiatry
  • Neuroscience

Background:

  • Catatonia is a complex psychomotor syndrome with potentially life-threatening features.
  • Historically, diagnostic clarity and operationalization have hindered catatonia research.
  • Benzodiazepines and electroconvulsive therapy (ECT) are established treatments.

Purpose of the Study:

  • To highlight the significance of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) classification of catatonia.
  • To underscore the need for further research into the pathobiology and neurobiology of catatonia.

Main Methods:

  • Review of clinical literature and diagnostic criteria evolution.
  • Discussion of neurobiological hypotheses including neurotransmitter systems (GABA, glutamate) and neuroimaging findings.
  • Analysis of the impact of the DSM-5 classification on research.

Main Results:

  • Catatonia is now recognized as a distinct syndrome, specifiable across various psychiatric and medical conditions in DSM-5.
  • Neuroimaging suggests altered activity in frontal and parietal motor areas.
  • Suspected neurotransmitter involvement includes GABA and glutamate.

Conclusions:

  • The DSM-5 classification provides a more precise concept of catatonia, facilitating research.
  • Increased clinical and neuroscientific research is anticipated, leading to a better understanding of catatonia's pathobiology.
  • More prospective trials are expected due to improved diagnostic criteria.
