About Dementia
When diagnosing dementia doctors first assess whether a patient has an underlying treatable condition such as depression, abnormal thyroid function, normal pressure hydrocephalus, or vitamin deficiency. Early diagnosis is important, some symptoms can be treated. In most cases, the specific type of dementia cannot be confirmed until after the patient has died and the brain can be examined.
Causes of Dementia
Doctors have identified many other conditions that can cause dementia-like symptoms. These conditions include:
- Creutzfeldt-Jakob disease, a rare brain disorder
- Huntington’s disease, a hereditary disorder caused by a faulty gene
- Chronic traumatic encephalopathy (CTE), caused by repeated traumatic brain injury
- Subdural hematoma, bleeding between the brain’s surface and its outer covering
Caring for a Person with Dementia
Many caregivers of older adults face difficult challenges when caring for people with dementia. Everyday tasks may seem endless from arranging doctor’s appointments, to transportation, feeding, and much more. Difficult situations, such as hospitalization and making decisions about long-term care, also arise.
