Link found between concussions, Alzheimer's disease

Concussions speed up Alzheimer's disease-related mind atrophy and cognitive decline for some folks, analysis exhibits.

New analysis has discovered concussions speed up Alzheimer's disease-related mind atrophy and cognitive decline in people who find themselves at genetic threat for the situation.
The findings, which seem within the journal Mind, present promise for detecting the affect of concussion on neurodegeneration.
Reasonable-to-severe traumatic mind damage is among the strongest environmental threat elements for creating neurodegenerative illnesses equivalent to late-onset Alzheimer's illness, though it's unclear whether or not gentle traumatic mind damage or concussion additionally will increase this threat.
Researchers from Boston College Faculty of Medication (BUSM) studied 160 Iraq and Afghanistan conflict veterans, some who had suffered a number of concussions and a few who had by no means had a concussion. Utilizing MRI imaging, the thickness of their cerebral cortex was measured in seven areas which are the primary to point out atrophy in Alzheimer's illness, in addition to seven management areas.
"We discovered that having a concussion was related to decrease cortical thickness in mind areas which are the primary to be affected in Alzheimer's illness," defined corresponding writer Jasmeet Hayes, PhD, assistant professor of psychiatry at BUSM and analysis psychologist on the Nationwide Middle for PTSD, VA Boston Healthcare System. "Our outcomes recommend that when mixed with genetic elements, concussions could also be related to accelerated cortical thickness and reminiscence decline in Alzheimer's illness related areas."
Of explicit be aware was that these mind abnormalities have been present in a comparatively younger group, with the common age being 32 years previous. "These findings present promise for detecting the affect of concussion on neurodegeneration early in a single's lifetime, thus it is very important doc the incidence and subsequent signs of a concussion, even when the particular person experiences solely having their "bell rung" and is ready to shake it off pretty shortly, on condition that when mixed with elements equivalent to genetics, the concussion could produce destructive long-term well being penalties," stated Hayes.
The researchers hope that others can construct upon these findings to seek out the exact concussion-related mechanisms that speed up the onset of neurodegenerative illnesses equivalent to Alzheimer's illness, persistent traumatic encephalopathy, Parkinson's and others. "Remedies could then sooner or later be developed to focus on these mechanisms and delay the onset of neurodegenerative pathology," she added.

Older, fitter adults experience greater brain activity while learning

In what is believed to be the first study of its kind, older adults who scored high on cardiorespiratory fitness (CRF) tests performed better on memory tasks than those who had low CRF. Further, the more fit older adults were, the more active their brain was during learning. These findings appear in the journal  Cortex . Difficulty remembering new information represents one of the most common complaints in aging and decreased memory performance is one of the hallmark impairments in Alzheimer's disease. Healthy young (18-31 years) and older adults (55-74 years) with a wide range of fitness levels walked and jogged on a treadmill while researchers assessed their cardiorespiratory fitness by measuring the ratio of inhaled and exhaled oxygen and carbon dioxide. These participants also underwent MRI scans which collected images of their brain while they learned and remembered names that were associated with pictures of unfamiliar faces. The researchers found that older adults, ...

Toxic brain cells may drive many neurodegenerative disorders, study finds

A study describing the findings will be published online Jan. 18 in  Nature . "We've learned astrocytes aren't always the good guys," said the study's senior author , Ben Barres, MD, PhD, professor of neurobiology, of developmental biology and of neurology and neurological sciences. "An aberrant version of them turns up in suspicious abundance in all the wrong places in brain-tissue samples from patients with brain injuries and major neurological disorders from Alzheimer's and Parkinson's to multiple sclerosis. The implications for treating these diseases are profound." Barres, who has spent three decades focusing on brain cells that aren't nerve cells, called the findings "the most important discovery my lab has ever made." Stanford postdoctoral scholar Shane Liddelow, PhD, is the study's lead author. Up to now, the pharmaceutical industry has mostly targeted nerve cells, also known as neurons, Barres said. But a broad...
