10 Early signs of Alzheimer’s Disease – Rush

Why it’s important to look beyond memory loss, and which behaviors to watch for. In my experience, everyone over 50 years old is concerned about their memory and cognitive powers.

Your dad just asked the same question he asked — and you answered — a few minutes ago. You realize that it’s not the first time he’s repeated himself or forgotten something you just said. What does this mean? Does he have Alzheimer’s disease?

Memory changes can be scary, both as an older adult experiencing them and as a family member or caregiver noticing them. But it’s important to note that forgetfulness doesn’t necessarily equal Alzheimer’s disease.

“The red flag is if it’s happening on a consistent basis and is paired with a change in the person’s ability to function,” says Magdalena Bednarczyk, MD, a geriatrician at Rush University Medical Center. “When a patient comes to me for an evaluation, it’s usually because family and friends have noticed uncharacteristic or concerning behaviors, not just memory issues.”

Brain’s ‘wiring insulation’ as major factor of age-related brain deterioration – Study

A new study led by the University of Portsmouth has identified that one of the major factors of age-related brain deterioration is the loss of a substance called myelin.

Myelin acts like the protective and insulating plastic casing around the electrical wires of the brain – called axons. Myelin is essential for superfast communication between nerve cells that lie behind the supercomputer power of the human brain.

The loss of myelin results in cognitive decline and is central to several neurodegenerative diseases, such as Multiple Sclerosis and Alzheimer’s disease. This new study found that the cells that drive myelin repair become less efficient as we age and identified a key gene that is most affected by ageing, which reduces the cells ability to replace lost myelin.
