Alzheimer's disease (AD) is the most common cause of dementia in elderly populations. Changes in the expression of the amyloid precursor protein (APP)-cleaving enzymes directly affect the formation of amyloid beta (Aβ) plaques, a neuropathological hallmark of AD.BACE1 mRNA level in AD subjects was significantly higher than those of healthy controls, whereas ADAM10 level was significantly lower in the AD subjects.

Patients who died of IS the most common type of dementia was vascular dementia while those died from other causes were most often diagnosed with Alzheimer's dementia (AD). Patients who died from IS and were registered in Riksstroke had higher MMSE score compared to other groups. Patients who died from IS took more cardiovascular medications. There were no differences in the use of antipsychotics, antidepressants, acetylcholinesterase inhibitors, memantine, anxiolytics, or hypnotics between the groups.

Nanomedicine is a field of science that employs materials in the nanometer scale.Alzheimer's disease (AD) and Parkinson's disease (PD) are the most common disorders worldwide, becoming a serious economic burden and public health problem.In this review, we have highlighted the potential of lipid nanoparticles in reaching the brain, a challenging task in modern medicine.

The most comprehensive genomic analysis of the human brain ever undertaken has revealed new insights into the changes it undergoes through development, how it varies among individuals, and the roots of neuropsychiatric illnesses such as autism spectrum disorders and schizophrenia.

Louis Populin and collaborators at the University of Wisconsin-Madison collaborators published a study this week in the Journal of Neuroscience describing increased connections between key parts of the brains of monkeys who have taken methylphenidate (Ritalin).
