Summary
Managing delirium involves non-pharmacologic approaches and treating underlying causes. Antipsychotics are recommended for psychosis and agitation, showing similar efficacy and safety across generations, and may help prevent delirium in certain patients.
Area of Science:
- Critical Care Medicine
- Geriatric Medicine
- Psychiatry
Background:
- Delirium management prioritizes non-pharmacologic interventions and addressing root causes.
- No specific FDA-approved medications exist for delirium-induced psychosis and agitation.
- Existing research is limited by small sample sizes, narrow criteria, and methodological variability.
Purpose of the Study:
- To review the current evidence and expert guidelines on pharmacologic management of delirium-related psychosis and agitation.
- To assess the efficacy and safety of antipsychotic medications in delirium.
- To explore the role of antipsychotics and dexmedetomidine in delirium prevention.
Main Methods:
- Systematic review of existing studies and expert guidelines.
- Analysis of comparative efficacy and safety data for first- and second-generation antipsychotics.
- Evaluation of evidence for delirium prevention strategies.
Main Results:
- Antipsychotics are supported by studies and guidelines for treating delirium-related psychosis and agitation.
- First- and second-generation antipsychotics demonstrate comparable efficacy and safety.
- Emerging evidence indicates antipsychotics and dexmedetomidine may prevent delirium in specific patient populations.
Conclusions:
- Antipsychotics are a key pharmacologic option for managing delirium symptoms, with no clear superiority between generations.
- Further research is needed to overcome limitations in current studies and establish definitive treatment protocols.
- Dexmedetomidine shows promise for delirium prevention in mechanically ventilated patients.

1.3K
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...

699
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.

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.

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.

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.

01:22Dementia l: Introduction
31
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
