Pathology News and Research

RSS

Pathology is the study and diagnosis of disease through examination of organs, tissues, bodily fluids, and whole bodies (autopsies). The term also encompasses the related scientific study of disease processes, called General pathology. Medical pathology is divided in two main branches, Anatomical pathology and Clinical pathology. Veterinary pathology is concerned with animal disease whereas Phytopathology is the study of plant diseases.

Donepezil slows brain shrinkage in some patients with mild cognitive impairment

According to a new study, the drug donepezil measurably slows the rate of brain shrinkage in some patients with mild cognitive impairment, a pre-Alzheimer's disease condition. The shrinkage was measured by magnetic resonance imaging (MRI).

Dopamine drug leads to new neurons and recovery of function in Parkinson's

In preliminary results, researchers have shown that a drug which mimics the effects of the nerve-signaling chemical dopamine causes new neurons to develop in the part of the brain where cells are lost in Parkinson's disease (PD).
