Summary
Combination antiretroviral therapy (cART) with superior central nervous system (CNS) penetration (neuroCART) may improve survival for patients with HIV-associated neurocognitive disorders (HAND). However, neuroCART can also cause CNS toxicity, necessitating further research.
Area of Science:
- Neuroscience
- Infectious Diseases
- Pharmacology
Background:
- HIV-associated neurocognitive disorders (HAND) remain prevalent, even in patients with suppressed viral loads.
- The CNS-penetrating effectiveness (CPE) scoring system aids in evaluating neuro-protective combination antiretroviral therapy (neuroCART) for HAND.
- Understanding the role of neuroCART in HAND is crucial for patient outcomes.
Purpose of the Study:
- To review cohort studies on the impact of neuroCART on the prevention, treatment, and survival of patients with HAND.
- To assess the effectiveness and potential risks of neuroCART in managing HAND.
Main Methods:
- Review of recent cohort studies examining combination antiretroviral therapy (cART) regimens.
- Analysis of studies focusing on central nervous system (CNS) penetration effectiveness (CPE) scores.
- Evaluation of neurocognitive outcomes and survival rates in patients with HAND.
Main Results:
- NeuroCART was linked to improved survival in children with HIV encephalopathy and adults with HIV-associated dementia.
- Optimal benefits of neuroCART were observed with high CPE scores and multi-drug regimens (>3 drugs).
- Emerging data indicate potential neurotoxicity and poorer neurocognitive performance with neuroCART in certain populations.
Conclusions:
- The precise therapeutic value of neuroCART for HAND requires further investigation.
- NeuroCART shows promise for improving survival in HIV dementia patients, but optimal regimens may vary.
- A randomized controlled trial is necessary to definitively establish the role of neuroCART in managing HAND.

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
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. They...
01:29Hepatic 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...
01:22Dementia l: Introduction
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...
01:29Alzheimer 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...
01:26Higher Mental Functions of Brain: Learning and Memory
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or playing an...
01:30Dementia
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.
The progression of dementia is generally gradual.
