There are seven stages of Alzheimer’s, dementia occurs in the mid to late stages of the disease.

Is being diagnosed with dementia means the person has Alzheimer’s?

No. Being diagnosed with dementia does not necessarily mean the person has Alzheimer’s. It simply means being diagnosed with a set of symptoms such as a decline in memory, thinking, and reasoning. Dementia may be due to various causes such as stroke and substance abuse, and not just Alzheimer’s. For the diagnosis of Alzheimer’s disease, your doctor needs to do specialized investigations such as a positron emission tomography (PET) scan besides physical examination and other tests.

Is there a cure for dementia and Alzheimer’s?

There is no cure for Alzheimer’s. The progression of the diseases can be stopped or slowed by various drug and non-drug options. Medical help must be sought as soon as the symptoms appear.

Dementia, however, may be cured in certain cases such as dementia due to certain medications and vitamin deficiencies.
