Positive Symptoms of Schizophrenia: Hallucinations and Delusions01:30

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

824
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...

Somatosensation01:33

Somatosensation

44.0K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

2.1K
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...

Overview of Protein Metabolism01:21

Overview of Protein Metabolism

4.3K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

2.2K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

1.5K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Summary
This summary is machine-generated.

Somatoparaphrenia, a delusion of body ownership, often follows right-hemisphere strokes. This review examines brain structures involved and presents three unique patient cases, including visceral and complex psychiatric manifestations.

Area of Science:

  • Neuroscience
  • Neurology
  • Psychiatry

Background:

  • Somatoparaphrenia (SP) is a rare delusion of body ownership.
  • It is frequently associated with damage to the right cerebral hemisphere, often following a stroke.
  • Patients typically deny ownership of their paralyzed limbs, particularly the left arm.

Purpose of the Study:

  • To review the neuroanatomical correlates of Somatoparaphrenia.
  • To present three distinct clinical cases illustrating the spectrum of SP.
  • To explore atypical presentations of SP, including visceral and psychiatric comorbidities.

Main Methods:

  • Literature review of studies investigating brain structures implicated in SP.
  • Clinical case series detailing three patients with SP.
  • Neuroimaging and clinical assessments were utilized.

Main Results:

  • Right-hemisphere structures, including the insula and temporoparietal junction, are commonly implicated in SP.
  • Case 1 presented typical SP involving the left hemiplegic hand.
  • Case 2 demonstrated SP affecting visceral sensations, and Case 3 showed a complex delusion with co-occurring psychiatric conditions.

Conclusions:

  • SP involves a network of right-hemisphere brain regions crucial for body ownership and self-awareness.
  • The condition can manifest in varied ways, extending beyond limb ownership to visceral sensations and complex delusions.
  • Understanding these diverse presentations is vital for accurate diagnosis and management.
