CD4 nadir is a predictor of HIV neurocognitive impairment in the era of combination antiretroviral therapy

Objective: Despite immune recovery in individuals on combination antiretroviral therapy (CART), the frequency of HIV-associated neurocognitive disorders (HANDs) remains high. Immune recovery is typically achieved after initiation of ART from the nadir, or the lowest historical CD4. The present study evaluated the probability of neuropsychological impairment (NPI) and HAND as a function of CD4 nadir […]

Incidence of dementia is increased in type 2 diabetes and reduced by the use of sulfonylureas and metformin

To determine incidence of dementia in type 2 diabetic (T2DM) patients, and whether there are adverse or favorable effects of oral agents (OA) in DM, we obtained a representative cohort of 800,000 from Taiwan’s National Health Insurance database. Those who, as of on January 1, 2000, were 50 years or older and dementia free (n […]

Treatment of Alzheimer’s disease with a cholinesterase inhibitor combined with antioxidants

A formula (formula F) was prepared to counteract oxidative stress (OS) in the brain. The formula contained the most common antioxidants and was intended to: (a) protect proteins, lipids, DNA and proteoglycans from oxidation (carnosine, coenzyme Q(10), vitamin E, vitamin C, beta-carotene, selenium, L-cysteine and ginkgo biloba); (b) reduce homocysteine (HCy) blood levels (vitamins B(6), […]

Validity of the free and cued selective reminding test in predicting dementia: the 3C study

Objective: We assessed the validity of the Free and Cued Selective Reminding Test (FCSRT) in predicting dementia 2 and 5 years after initial evaluation in a population-based cohort over age 65 years participating in the French 3 Cities (3C) study.; Methods: The FCSRT was administered at baseline along with demographics, cognitive and functional scales, and […]

Addenbrooke’s Cognitive Examination validation in Parkinson’s disease

Background: There is a clear need for brief, sensitive and specific cognitive screening instruments in Parkinson’s disease (PD).; Objectives: To study Addenbrooke’s Cognitive Examination (ACE) validity for cognitive assessment of PD patient’s using the Mattis Dementia Rating Scale (MDRS) as reference method. A specific scale for cognitive evaluation in PD, in this instance the Scales […]

Efficacy of a vitamin/nutriceutical formulation for moderate-stage to later-stage Alzheimer’s disease: a placebo-controlled pilot study

Recent studies demonstrated efficacy of a vitamin/ nutriceutical formulation (folate, vitamin B12, alpha-tocopherol, S-adenosyl methionine, N-acetyl cysteine, and acetyl-L-carnitine) for mild to moderate Alzheimer’s disease. Herein, we tested the efficacy of this formulation in a small cohort of 12 institutionalized patients diagnosed with moderate-stage to later-stage Alzheimer’s disease. Participants were randomly separated into treatment of […]
