In brief: No

Alzheimer's is one type of dementia-causing pathology.
Other causes are head injury, vascular problems/stroke, tiny pathogens (pick's disease, for one), parkinson's, huntington's, extensive drug/alcohol abuse, and more. 'senility' is now a non-standard term that refers generally to dementia or less severe age-related cognitive decline.

In brief: Careful

This sounds like real concern being masked by semantics.

Agreed--information alone may not be the only desire here; if you are concerned about yourself or a loved one in regard to cognitive changes, consider consulting with a psychiatrist, neurologist, or neuropsychologist. 'Senile' is a term that has come to be used both informally in a dismissive or non-serious context and also in terms of some serious meanings. Please consult if truly concerned.
