Frontotemporal dementia is associated with alterations in immune system function

Researchers discovered increased inflammatory activity in a subgroup of patients with frontotemporal dementia. The increased inflammation was indicated by elevated levels of cytokines known to increase inflammatory response and decreased levels of IL-10, which reduces inflammation. The inflammation was associated with Parkinsonism's symptoms and rapid cognitive and functional decline. The study also revealed patients with FTD are less likely to develop cancer.... Read More...

Study pinpoints Alzheimer’s plaque emergence early and deep in the brain

Researchers use SWITCH technology to label amyloid plaques in mouse models of Alzheimer's disease so they could be imaged in fine detail at different ages. They were consistently able to see the plaques first emerged in deep brain structures and tracked circuits, such as the Papez memory circuit, to spread throughout the brain as the animal aged....

Walking patterns can identify dementia type

People with two common types of dementia, Lewy body dementia, and Alzheimer's disease, have unique walking patterns. The gait type signals subtle differences between the two disorders. Those with Lew body dementia change their steps more, varying the step time and length. They also display more asymmetry in movement compared to those with Alzheimer's disease. Researchers say gait could be a clinical biomarker for dementia subtypes.... Read More...

How the eyes might be windows to the risk of Alzheimer’s disease

Adults with mild cognitive impairment (MCI), a precursor to Alzheimer's disease, have greater pupil dilation when taking cognitive tests than their cognitively normal peers. Task-evoked pupillary response may be a cost-effective, and low invasive screening test for those at genetic risk for Alzheimer's before the symptoms of the disease take hold. ... Read More...

Poor oral health linked to cognitive decline and perceived stress

Poor oral health has been linked to cognitive decline and increased symptoms of stress. Stress increases symptoms of dry mouth, which can lead to poor overall oral health. Those with tooth related symptoms, such as toothaches and cavities, are more likely to experience declines in cognition and episodic memory.... Read More...

Map of broken brain networks shows why people lose speech in language-based dementia

Researchers have identified the location of dysfunctional brain networks that lead to impaired sentence production and word-finding in primary progressive aphasia (PPA). PPA can occur in those with neurodegenerative diseases, such as frontotemporal dementia and Alzheimer's disease. Mapping the networks allows clinicians to apply non-invasive brain stimulation to potentially improve speech in those with PPA. ... Read More...
