Migraines linked to higher risk of dementia

Dementia is the most common neurological disease in older adults, whereas headaches, including migraines, are the most common neurological disorder across all ages. In a recent study that included 679 community-dwelling adults aged 65 years and older, migraines were a significant risk factor for dementia, including Alzheimer’s disease.

Soldiers, athletes could improved outcomes from traumatic brain injuries

A traumatic brain injury is often easily suspected and can be confirmed and treated if necessary following an injury using a blood analysis, but scientists are reporting that even one mild blast to the brain can cause very subtle but permanent damage as well. Urine analysis taken within one week of a mild to traumatic brain injury also can provide faster diagnosis and treatment for such injuries.

Scientists link ‘hunger hormone’ to memory in Alzheimer’s study

Scientists have found evidence suggesting that resistance to the ‘hunger hormone’ ghrelin in the brain is linked to the cognitive impairments and memory loss associated with Alzheimer’s disease (AD). The findings, based on observations of postmortem brain-tissue samples from Alzheimer’s patients and on experiments with a mouse model of AD, also suggest a possible treatment strategy for the incurable neurodegenerative disorder.

Enzyme known for promoting cancer found to also protect healthy cells

New research reveals a new role for the enzyme telomerase, which scientists thought was turned off in most normal adult cells, except in cancerous tumors where it promotes unlimited cell division. The researchers discovered that as normal, healthy adult cells approach cell-death, they produce a burst of telomerase that prevents malignancies and softens the final steps in the aging process.
