Bipolar Disorder01:30

Bipolar Disorder

754
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.

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

1.7K
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...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Bipolar Junction Transistor01:22

Bipolar Junction Transistor

1.5K
Bipolar Junction Transistors (BJTs) are essential elements in electronic circuits, playing a crucial role in the functionality of amplifiers, memories, and microprocessors. These transistors can be designed as NPN or PNP based on their doping patterns. They consist of three layers: the emitter, base, and collector. The configuration of these layers and their respective doping levels—with N-type or P-type impurities—define the transistor's type and its operational...

Drug Abuse and Addiction: Pharmacological Phenomena

1.3K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Epidemiology

Background:

  • Behavioral addictions (BA) are linked to various psychiatric disorders.
  • The comorbidity between BA and bipolar disorders (BD) requires further investigation.

Purpose of the Study:

  • To systematically review and evaluate evidence on the association between BA and BD.
  • To summarize prevalence, features, and treatment of BA-BD comorbidity.

Main Methods:

  • Systematic review of major electronic databases (inception to Dec 2017) following PRISMA guidelines.
  • Inclusion of quantitative studies reporting on BA-BD comorbidity.
  • Narrative synthesis of data from 28 selected articles out of 1250 initial studies.

Main Results:

  • BA may be overrepresented in BD samples and vice versa.
  • Pathological gambling and kleptomania were most prevalent BA, followed by compulsive buying, sexual behavior, and internet addiction.
  • BA-BD comorbidity is associated with a more severe illness course and other psychiatric conditions like mood, anxiety, and substance use disorders.

Conclusions:

  • Behavioral addictions and bipolar disorders commonly co-occur, impacting illness severity.
  • Limited research exists on treatment strategies for BA-BD comorbidity.
  • Routine screening for BA in BD patients is advised for early identification and management.
