Sufferers who’re at greater danger embrace these on blood thinners, those that have had greater than 4 microscopic bleeds within the mind and people with an Alzheimer’s-linked gene mutation known as APOE4 — particularly if they’ve two copies of the mutation. They, together with their docs, ought to contemplate whether or not the elevated security danger outweighs their want for a medicine that may modestly gradual cognitive decline.

A big scientific trial of the drug discovered that just about 13 % of sufferers receiving Leqembi skilled mind swelling, however most of these instances have been gentle or average. Lower than 2 % of sufferers receiving the placebo skilled such swelling. Most mind swelling didn’t trigger any signs and customarily resolved inside a couple of months.

To study these dangers, ask for genetic testing to find out when you have the APOE4 gene mutation. Individuals with two copies of that mutation — about 15 % of Alzheimer’s sufferers — are at particularly excessive danger of mind swelling and bleeding.

There are different elements to think about too. Would going to a clinic for a drug infusion each two weeks pose a burden?

And, importantly, how do you and your loved ones understand your present cognitive situation and the way it impacts your life?
