How Useful is Amyloid PET Imaging in the Diagnosis of Dementia?
In a prospective, observational study in multiple centers in Italy, amyloid PET imaging was shown to be negative in 35% of patients who met clinical criteria for a diagnosis of Alzheimer’s disease.

Alzheimer’s Disease: What the Primary Care Physician Needs to Know
This article explores current medical approaches to Alzheimer’s dementia, the most common subtype of the known dementias or neurocognitive disorders. Preventive treatment is at the forefront of efforts to defeat this progressively impairing disorder; but to be effective, intervention must start well before symptoms begin. The role of the primary care provider in initiating vigorous and early preventive measures and applying appropriate pharmacologic and non-pharmacologic interventions at each stage of disease progression is reviewed and discussed.

Eating Behavior in Frontotemporal Dementias
In a prospective, controlled study of 49 patients with dementia and 25 healthy controls, marked hyperphagia is restricted to behavioral-variant frontotemporal dementia patients that is likely due to differing neural networks, while increased sucrose preference is likely controlled by a similar network in both behavioral-variant frontotemporal dementia and semantic dementia patients.

Cerebrospinal Fluid Tau and Amyloid-ß1-42 in Patients with Dementia
In patients with clinically diagnosed dementia, the CSF biomarker profile of low CSF amyloid-ß1-42, high total tau, and high phosphorylated tau was seen in the majority of patients with clinically diagnosed Alzheimer’s disease. Substantial proportions of patients with non-Alzheimer’s dementia were also found to have the Alzheimer’s disease pathological profile. The value of CSF biomarker measurements in clinical practice is uncertain.

Omega-3s for the AREDS2 Cohort Are Not Beneficial for Preventing Cognitive Decline
A sub-analysis of the AREDS2 randomized, controlled trial that involved supplemental omega-3 fatty acids failed to find benefit on cognitive function over 5 years.

Migraine and Cognitive Dysfunction
During an attack of migraine without aura, patients may experience transient cognitive impairment, with predominant involvement of verbal processing speed, learning, and memory, due to reversible cortical dysfunction.

Statin Use and Cognitive Effects: Not a Brain Drain
Despite earlier concerns by the FDA about adverse effects of statins on cognitive functioning, a meta-analysis of data from more than 28,000 patients enrolled in 18 randomized, placebo-controlled trials of statin therapy failed to show a causal relationship between treatment and adverse neurocognitive effects for patients with and without cognitive impairment.

Can Dietary Intervention Delay the Onset of Alzheimer’s Disease?
In a prospective study of an elderly population, moderate adherence to the MIND diet was associated with a 53% reduction in the development of Alzheimer’s disease.

Cerebrospinal Fluid Biomarkers of Neuronal Injury in Mild AD
Cerebrospinal fluid visinin-like protein 1 is a useful marker, along with CSF tau and phospho-tau measurements, to predict brain atrophy and neurodegeneration in patients who carry a clinical diagnosis of Alzheimer’s disease.

A Nutritional Approach to Prevent Alzheimer’s Disease
Moderate and high adherence to a blend of the Mediterranean and DASH diets helped to slow cognitive decline over 4.5 years in a cohort aged 58 years and older.
