The symptoms depend on which part of his brain was affected by the stroke. While Alzheimer's usually begins with memory problems, vascular dementia more often begins with poor judgment or trouble planning, organizing, and making decisions.
Landlords are not responsible for the loss of personal property of a tenant after a fire. This is because the landlord had no control over the fire or over what property the tenants decided to keep in the rental unit.
When tenants rent an apartment or house, they often assume the insurance the building's owner has covers them. Unfortunately, this is not correct. Your landlord has insurance for structural damage to the building. However, the landlord's insurance does not cover your personal property. Damage to your personal property is not covered by your landlord's insurance policy, even if it results from damage to the building from events like fire, windstorms or flooding.
