Summary
Cognitive impairment is a core feature of schizophrenia, impacting social and occupational outcomes. Newer antipsychotics may offer some cognitive benefits, but further research and non-pharmacological interventions are needed.
Area of Science:
- Neuroscience
- Psychiatry
- Pharmacology
Background:
- Cognitive impairment is a central characteristic of schizophrenia, affecting attention, memory, and executive functions.
- It is increasingly recognized as a primary, enduring deficit, not solely a consequence of positive or negative symptoms.
- These cognitive deficits significantly impact long-term social and occupational functioning.
Purpose of the Study:
- To discuss cognitive impairment in schizophrenia.
- To review the therapeutic effects of newer antipsychotic agents on cognitive functioning.
Main Methods:
- Literature review and discussion of existing research on cognitive deficits in schizophrenia.
- Analysis of the impact of newer antipsychotic medications on cognitive domains.
Main Results:
- Cognitive dysfunction precedes the first psychotic episode and persists throughout schizophrenia.
- Newer antipsychotics may improve cognitive functioning indirectly through better symptom control and fewer side effects, or directly via effects on brain activity.
- However, these medications do not fully normalize neurocognitive deficits.
Conclusions:
- Cognitive impairment is a persistent and impactful aspect of schizophrenia.
- While newer antipsychotics show promise for cognitive improvement, they are not a complete solution.
- Non-pharmacological interventions are also crucial for cognitive rehabilitation in schizophrenia.

01:26Psychosis: Goals of Pharmacotherapy
446
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

01:22Alzheimer's Disease: Treatment
764
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

01:30Negative and Cognitive Symptoms of Schizophrenia
411
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

01:28Psychosis and Antipsychotic Drugs: Overview
779
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...

01:28Drug Therapy
232
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
517
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.
