Alzheimer's & Dementia

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities.

Alzheimer’s Disease | Definition, Causes, Diagnosis & Treatment

Alzheimer’s Disease (AD) is the most common form of dementia worldwide (60-70% of all dementia cases) and is a progressive neurodegenerative disorder.

A wife’s account reveals the hidden burden of young-onset Alzheimer’s caregiving

Karina Acton Reid recounts caring for her husband with young-onset Alzheimer’s disease presenting as posterior cortical atrophy while raising two young children. Her perspective shows how visual disorientation, diagnostic delays, changing family roles, and inadequate age-appropriate support affect the entire household.

Blood p-tau217 levels signal cognitive impairment risk years before symptoms emerge

Higher baseline plasma p-tau217 was associated with greater 5- and 10-year risks of cognitive impairment and faster cognitive decline among 2,684 cognitively unimpaired adults. Very high levels corresponded to an estimated 38% risk at five years, but selected cohorts and limited long-term data mean routine screening and individualized prediction remain premature.

Researchers identify new genetic pathway driving epilepsy and seizures

Researchers have uncovered a novel biological pathway that can lead to seizures when disrupted. The findings also provide a new approach to improve the diagnosis of epilepsy, for which a genetic cause cannot be found in about 50 % of individuals with the condition

Sleeping longer may signal early Alzheimer's-related brain changes

Regularly sleeping long hours each night is associated with higher levels of an Alzheimer's-related protein in the blood, even accounting for other health factors, suggests a new study from UT Health San Antonio, the academic health center of The University of Texas at San Antonio.

Brain’s immune cells play key role in maintaining stability of neuronal networks in Alzheimer's disease

Researchers at Trinity College Dublin have discovered that microglia – the main immune cells of the brain – play a critical role in maintaining the stability of neuronal networks in Alzheimer's disease.

Study sheds light on the prognostic value of blood test for predicting cognitive impairment risk

A blood test for the biomarker phosphorylated tau 217 (p-tau217) recently received federal clearance, but questions have emerged around the extent to which such tests can accurately predict whether a cognitively healthy individual will go on to develop cognitive impairment-a key symptom of Alzheimer's disease.
