Neurocognitive disturbances in HIV
1HIV Neurobehavioral Research Center (HNRC), University of California, San Diego, USA.
Summary
HIV infection can cause brain issues known as HIV-associated neurocognitive disorder (HAND). Neurocognitive examinations are crucial for detecting and tracking these changes, considering factors that influence their development.
Area of Science:
- Neuroscience
- Infectious Diseases
- Neurology
Background:
- Human Immunodeficiency Virus (HIV) infection impacts central nervous system function.
- HIV-associated neurocognitive disorder (HAND) encompasses a spectrum of cognitive impairments.
- Understanding HAND is critical for managing long-term health outcomes in HIV patients.
Purpose of the Study:
- To review current approaches for evaluating neurocognitive disturbances in HAND.
- To highlight the sensitivity and relevance of neurocognitive examinations in HAND detection and monitoring.
- To discuss cofactors influencing the manifestation of HAND.
Main Methods:
- Review of existing literature on neurocognitive assessment in HIV.
- Analysis of methods used to evaluate diverse neurocognitive deficits.
- Consideration of influencing factors and cofactors in HAND.
Main Results:
- Neurocognitive examination is a key tool for identifying and monitoring HAND.
- Various methods exist to assess different facets of neurocognitive impairment.
- Cofactors play a significant role in the presentation and severity of HAND.
Conclusions:
- Neurocognitive assessment is essential for the clinical management of HIV patients.
- A comprehensive approach is needed to understand and address HAND.
- Further research into cofactors can refine diagnostic and therapeutic strategies.

Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Hepatic Encephalopathy
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
Disorders of the Nervous Tissue
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

Negative and Cognitive Symptoms of Schizophrenia
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,...

Alzheimer Disease l: Introduction
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
Alzheimer's Disease: Overview
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...
