Nailing down the exact causes of Alzheimer's is tough, sparking endless queries. " Is Alzheimer's genetic? " is a common question on the lips of many healthcare folks and brain researchers. Alzheimer's disease is divided into two types: late-onset—the usual suspect—and early-onset—which shows up unexpectedly earlier in life.
Both share certain genetic quirks, especially the ε4 variant in the APOE gene, which is known to increase the risk for late-onset Alzheimer's. Wondering about the tell-tale signs? Well, they're a mixed bag but generally include memory loss that just keeps getting worse, unexpected mood flips or personality tweaks, trouble making plans or solving problems, frequent mix-ups with places or times, and a tough time handling daily routines. These symptoms creep up slowly, reshaping the lives of those affected and their close ones bit by bit.
The key difference between the early and late types is when they start. Early-onset, which is very rare, shows up in your 30s, 40s, or 50s. Late-onset usually waits until after 65.
Genes definitely play a part in Alzheimer's. Sometimes, a single faulty gene or a combo of mutations can raise your risk. In families with a strong genetic link, it can even follow a pattern where children have a 50/50 shot of inheriting the gene for early-onset.
But it's not just your genes. The aforementioned age, exercise level, diet, and activities that promote the health of the heart and brain can play a role in .
