Study Notes
Types of Schizophrenia
- Paranoid Schizophrenia: Characterized by intense, irrational beliefs of being persecuted or conspired against.
- Disorganized Schizophrenia: Features disorganized speech and behavior, leading to impaired functioning.
- Catatonic Schizophrenia: Involves extreme motor disturbances, including catatonia, where individuals may remain still for long periods.
- Residual Schizophrenia: Symptoms are present but less intense, often after a more acute episode.
Positive and Negative Symptoms
- Positive Symptoms: Include hallucinations (often auditory) and delusions (fixed false beliefs), adding abnormal behaviors.
- Negative Symptoms: Involve deficits in normal emotional responses, such as lack of motivation, reduced emotional expression, and social withdrawal.
Freeman et al. Study on Virtual Reality
- Investigated the use of virtual reality environments to replicate social situations for patients with paranoia.
- Participants experienced social scenarios while their responses were monitored to understand triggers of paranoid thoughts.
- Findings suggest that virtual reality can be a useful tool in treatment by helping individuals confront and challenge paranoid beliefs.
Treatments for Schizophrenia
- Antipsychotic Medications: Primarily target neurotransmitters (e.g., dopamine) to alleviate symptoms; includes atypical (e.g., clozapine) and typical (e.g., haloperidol) antipsychotics.
- Cognitive Behavioral Therapy (CBT): Focuses on modifying dysfunctional thoughts related to schizophrenia, promoting coping strategies.
- Electroconvulsive Therapy (ECT): May be used in severe cases unresponsive to medication; involves inducing seizures to relieve symptoms but is less common.
Cognitive Explanations for Schizophrenia
- Cognitive Deficits: Impaired thinking processes and difficulties with attention, memory, and executive functioning are common in individuals with schizophrenia.
- Metacognitive Beliefs: Faulty beliefs about one's thinking can lead to misinterpretation of experiences, contributing to the development of paranoid delusions.
- Information Processing: The theory suggests that individuals with schizophrenia struggle with integrating and interpreting sensory input effectively, leading to distorted experiences.
