Dissociative Disorders01:27

Dissociative Disorders

513
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

558
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...

Adrenergic Receptors: ɑ Subtype01:31

Adrenergic Receptors: ɑ Subtype

2.8K
Adrenoceptors are classified into α and ꞵ classes based on their potencies to catecholamine agonists. α-adrenoceptors show the following order of catecholamine potency:
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase...

Adrenergic Receptors: β Subtype01:26

Adrenergic Receptors: β Subtype

3.7K
β-adrenoceptors have varied sensitivities towards adrenaline, noradrenaline, and isoprenaline. The order of agonist potency is as follows:
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.

Diabetes Mellitus: Overview and Type I Subtype01:22

Diabetes Mellitus: Overview and Type I Subtype

5.0K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Dissociative Identity Disorder01:30

Dissociative Identity Disorder

819
Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...

Summary

The new Dissociative Subtype of PTSD Interview (DSP-I) effectively assesses post-traumatic stress disorder with dissociative subtype (PTSD-DS). This validated tool aids clinicians in identifying and differentiating crucial dissociative symptoms in trauma survivors.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Trauma Studies

Background:

  • The DSM-5 recognizes the dissociative subtype of PTSD (PTSD-DS), highlighting the need for accurate assessment tools.
  • Trauma-related dissociative symptoms, including depersonalization and derealization, require careful clinical evaluation.

Purpose of the Study:

  • To introduce and validate the Dissociative Subtype of PTSD Interview (DSP-I), a clinician-administered instrument.
  • To assess the psychometric properties and clinical utility of the DSP-I for PTSD-DS and related dissociative symptoms.

Main Methods:

  • The DSP-I was developed to assess PTSD-DS and includes a supplementary checklist for other dissociative symptoms.
  • Psychometric properties were evaluated in treatment-seeking individuals with PTSD and histories of multiple trauma.

Main Results:

  • The DSP-I demonstrated high internal consistency and good convergent and divergent validity.
  • The instrument explained an additional 8% of variance in PTSD severity beyond existing measures.
  • The supplementary checklist showed strong associations with general distress and related symptoms.

Conclusions:

  • The DSP-I is a clinically relevant and psychometrically sound instrument for assessing PTSD-DS.
  • The DSP-I is valuable for both clinical practice and research settings involving trauma survivors.
