These common drugs may raise your risk of dementia

These common drugs may raise your risk of dementia

A landmark study has linked the long-term use of certain anticholinergic drugs to a higher risk of dementia later on. Several common drugs may put you at higher risk of dementia later in life. This investigation is believed to be the “largest and most detailed” study to date into long-term anticholinergic use and dementia risk. […]

Cognitive decline: Impaired sense of smell could be used as marker

Cognitive decline: Impaired sense of smell could be used as marker

Testing for sense of smell in adults aged 65–74 may identify those at higher risk of cognitive decline, according to a new study from Germany that is now published in the Journal of Alzheimer’s Disease. Olfactory dysfunction could mean a higher risk of cognitive decline. Cognitive decline refers to the decline of mental functions such […]

How the brain’s ‘immune memory’ may lead to Alzheimer’s

How the brain’s ‘immune memory’ may lead to Alzheimer’s

A new study shows that microglia, which are the immune cells of the central nervous system, can “remember” inflammation. This “memory” influences how the cells react to new stimuli and deal with toxic plaque in the brain, a marker of Alzheimer’s disease. The brain’s immune cells remember previous inflammation. Microglia, sometimes referred to as “scavenger” […]

Breakthrough: Researchers fix Alzheimer’s gene

Breakthrough: Researchers fix Alzheimer’s gene

Groundbreaking research shows, for the first time, how the most well-known genetic risk factor for Alzheimer’s disease causes signs in human brain cells. Also, the scientists managed to correct the gene and erase its harmful effects. Scientists fix the faulty gene that most likely causes Alzheimer’s. The complex role of the apolipoprotein (APOE) gene in […]

Alzheimer’s: Scientists find the cause of evening agitation

Alzheimer’s: Scientists find the cause of evening agitation

A new study has uncovered a biological clock circuit that may explain why people with Alzheimer’s disease or other forms of dementia can become more agitated or aggressive in the early evening. People with Alzheimer’s can feel more agitated during the evening. The researchers hope that their findings will lead to new treatments that help […]

Blood test detects Alzheimer’s before symptoms appear

Blood test detects Alzheimer’s before symptoms appear

A group of researchers is close to developing a blood test that can detect Alzheimer’s disease long before symptoms appear. The test will be extremely useful for scientists trying to understand and treat the condition. A simple blood test may predict Alzheimer’s years earlier than is currently possible. One of the major issues that hamper […]

Coffee may worsen Alzheimer’s symptoms

Coffee may worsen Alzheimer’s symptoms

At Medical News Today, we often report on studies yielding the health benefits of drinking coffee. New research, however, now suggests that our beloved cup of joe might have a darker side, after finding that long-term caffeine intake could exacerbate symptoms of Alzheimer’s disease. Researchers suggest that long-term caffeine consumption may worsen the behavioral symptoms […]

Low dopamine may indicate early Alzheimer’s

Low dopamine may indicate early Alzheimer’s

A new study reports a newly discovered link between the loss of dopamine-firing cells in the brain and the brain’s ability to form new memories. It questions the implications of these findings rgearding Alzheimer’s disease. Low dopamine levels may indicate Alzheimer’s disease. Dopamine is a neurotransmitter that is involved in regulating emotional responses and movement. […]

Ibuprofen could stop Alzheimer’s, say researchers

Ibuprofen could stop Alzheimer’s, say researchers

You may have taken ibuprofen today, be it to ease a headache or alleviate back pain. But there might be more to this common medication than pain relief; a new paper suggests that a daily dose of ibuprofen could prevent Alzheimer’s disease. Researchers say that ibuprofen could ward off Alzheimer’s if taken every day. Led […]

Alzheimer’s: This protein may halt brain injury

Alzheimer’s: This protein may halt brain injury

Antibodies that can remove toxic protein plaques in the brains of mice may lead to treatments that halt the brain damage caused by Alzheimer’s disease. What role do antibodies (depicted here) have in treating Alzheimer’s? This was the conclusion that researchers came to after investigating antibodies that target the apolipoprotein E (APOE) protein in a […]
