Brain Cells Die in Alzheimer’s and FTD

In the brain, LSD1 (lysine specific histone demethylase 1) maintains silence among genes that are supposed to be turned off. When the researchers engineered mice that have the LSD1 gene snipped out in adulthood, the mice became cognitively impaired and paralyzed. Plenty of neurons were dying in the brains of

Brain Cells Found to Control Aging

The hypothalamus was known to regulate important processes including growth, development, reproduction and metabolism. In a 2013 Nature paper, Einstein researchers made the surprising finding that the hypothalamus also regulates aging throughout the body. Now, the scientists have pinpointed the cells in the hypothalamus that control aging: a tiny population of adult

Physical Exercise Prevents Dementia

In order to further advance current state of knowledge on the positive influence of physical activity on the brain, gerontologists and sports physicians at Goethe University Frankfurt have examined the effects of regular exercise on brain metabolism and memory of 60 participants aged between 65 and 85 in a randomised

The Brain’s Rejuvenating Cells

The brain is a fragile and unique organ that has its own specially tailored immune system, separate from the rest of the body. The primary role of the brain's immune cells, called microglia, is to recognize, disassemble, and dispose of various substances that do not function properly in the brain,

Eating Green Leafy Vegetables Keeps Mental Abilities Sharp

Something as easy as adding more spinach, kale, collards and mustard greens to your diet could help slow cognitive decline, according to new research. The study also examined the nutrients responsible for the effect, linking vitamin K consumption to slower cognitive decline for the first time. "Losing one's memory or cognitive

Drug Treatment Could Combat Hearing Loss

Within the inner ear, thousands of hair cells detect sound waves and translate them into nerve signals that allow us to hear speech, music, and other everyday sounds. Damage to these cells is one of the leading causes of hearing loss, which affects 48 million Americans. Each of us is born

Air Pollution May Lead to Dementia in Older Women

Tiny air pollution particles -- the type that mainly comes from power plants and automobiles -- may greatly increase the chance of dementia, including Alzheimer's disease, according to USC-led research. Scientists and engineers found that older women who live in places with fine particulate matter exceeding the U.S. Environmental Protection Agency's

Eye Muscles are Resilient to ALS

Amyotrophic Lateral Sclerosis, commonly known as ALS, is an incurable neurodegenerative disease that affects all voluntary muscles in the body leading to paralysis and breathing difficulties. Eye muscles, in contrast to other muscles, generally retain their mobility even in the final stages of the disease. A dissertation at Umeå University in
