Dissociative Disorders01:27

Dissociative Disorders

557
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

Dissociative Amnesia01:21

Dissociative Amnesia

585
Dissociative amnesia is a complex psychological condition that manifests as an inability to recall personal information, often tied to traumatic or stressful events. Unlike general amnesia, individuals with this condition retain the ability to perform routine activities and procedural tasks, such as operating a phone or navigating public transportation, yet experience profound gaps in autobiographical memory. These lapses may encompass significant life events, such as suicide attempts or...

Oxidation of Alcohols02:37

Oxidation of Alcohols

16.0K
In this lesson, the oxidation of alcohols is discussed in depth. The various reagents used for oxidation of primary and secondary alcohols are detailed, and their mechanism of action is provided.
The process of oxidation in a chemical reaction is observed in any of the three forms:

Relative Risk01:12

Relative Risk

2.1K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis

12.9K
Overview
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

Protection of Alcohols02:31

Protection of Alcohols

8.1K
This lesson delves into the concept of protection and deprotection of a functional group fundamental to synthetic organic chemistry. These phenomena are explained in the context of aliphatic and aromatic alcohols.
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...

Summary

Alcohol intoxication increases the risk of deliberate self-harm (DSH). This study found that while alcohol affects DSH, the dissociative effects of alcohol do not mediate this relationship.

Area of Science:

  • Psychology
  • Neuroscience
  • Public Health

Background:

  • Alcohol intoxication is a known risk factor for deliberate self-harm (DSH).
  • The precise mechanisms linking alcohol consumption to DSH remain unclear.
  • Dissociation is a proposed mediating factor in the alcohol-DSH relationship.

Purpose of the Study:

  • To investigate whether alcohol-induced dissociation mediates the association between alcohol intoxication and deliberate self-harm.
  • To examine the relationship between blood alcohol concentration (BAC), dissociation, and DSH behavior.

Main Methods:

  • A dose-response study design was employed.
  • Participants achieved target blood alcohol concentrations (BAC) from 0.00% to 0.10%.
  • Dissociation was measured using the Alcohol Dissociative Experiences Scale, and DSH was assessed behaviorally.

Main Results:

  • Blood alcohol concentration (BAC) was found to predict both dissociation and deliberate self-harm (DSH).
  • However, dissociation did not significantly predict DSH in this study.
  • The findings indicate that dissociation does not mediate the effect of alcohol on DSH.

Conclusions:

  • Contrary to some clinical observations, alcohol-induced dissociation does not appear to mediate the link between alcohol intoxication and deliberate self-harm.
  • Further research is needed to elucidate the complex mechanisms underlying alcohol's role in DSH.
