In brief: Alcohol

We have no evidence alzheimer's is caused by a drug.
However chronic excessive alcohol use is associated with dementia. There are negative cognitive effects of many other drugs including marijuana and opiates but few dementia syndromes described. To cause dementia there would need to be brain damage.

In brief: There are many

Agents that can contribute to cognitive decline although none are known to specificallly cause alzheimer's disease.
In general it is best to avoid what are known as anti-cholinergic agents in the elderly since these can cause side effects including cognitive worsening.

In brief: Pseudo dementia

Drugs do not cause alzheimer's, but numerous medicines can make it far worse due to anti-cholinergic side effects, and many elderly pts can seem to be demented due to drug effects, which reverse when med is modified.
