no, it’s not something infectious. alzheimer’s disease is a degenerative disease that progressively destroys the memory pathways in your brain. Abnormal deposits of proteins form amyloid plaques and neuron tangles throughout the brain, and once-healthy neurons begin to work less efficiently. Over time, neurons lose their ability to function and communicate with each other, and eventually they die.
There is another disease that involves abnormal protein in the brain which is infectious. Its called Creutzfeldt-Jakob disease – its a bit like mad cow disease. it is caused when a normal brain protein misfolds into what we call a prion. It can cause other proteins like it to misfold spreading the prions and it can be transmitted between people. People with Creutzfeldt-Jakob disease have many neurological symptoms including behavioural changes, blindness, weakness, loss of balance, difficulty walking or speaking and muscle spasm. It can also progress to dementia.
No it is not infectious! But the early-onset form of Alzheimer disease is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In most cases, an affected person inherits the altered gene from one affected parent. I was worried about my father when I lost both my grandparents due to Alzheimer’s but luckily their Alzheimer is not inheritable…
