Do you see a neurologist for memory loss?

He or she may also order blood tests and brain-imaging tests that can help identify reversible causes of memory problems and dementia-like symptoms. You might be referred to a specialist in diagnosing dementia or memory disorders, such as a neurologist, psychiatrist, psychologist or geriatrician.

What condition can be mistaken for dementia?

How do doctors know if you have Alzheimer’s?

Carry out standard medical tests, such as blood and urine tests, to identify other possible causes of the problem. Perform brain scans, such as computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET), to rule out other possible causes for symptoms.

What can a brain scan reveal?

CT scans, which use X-rays to detect brain structures, can show evidence of brain atrophy, strokes and ischemia, changes to the blood vessels, and other problems such as hydrocephalus and subdural hematomas. MRI scans use magnetic fields and focused radio waves to detect hydrogen atoms in tissues within the body.

Can a brain scan show mental illness?

Brain scans alone cannot be used to diagnose a mental disorder, such as autism, anxiety, depression, schizophrenia, or bipolar disorder. In some cases, a brain scan might be used to rule out other medical illnesses, such as a tumor, that could cause symptoms similar to a mental disorder, such as depression.

What is the difference between dementia and vascular dementia?

The word dementia describes a set of symptoms that can include memory loss and difficulties with thinking, problem-solving or language. In vascular dementia, these symptoms occur when the brain is damaged because of problems with the supply of blood to the brain.

Can dementia be seen on a brain scan?

Brain scans. These tests can identify strokes, tumors, and other problems that can cause dementia. Scans also identify changes in the brain’s structure and function.

Can a brain scan tell if you have Alzheimer’s?

Brain scans CT and MRI scans, which reveal the anatomic structure of the brain, are used to rule out such problems as tumor, hemorrhage, stroke, and hydrocephalus, which can masquerade as Alzheimer’s disease. These scans can also show the loss of brain mass associated with Alzheimer’s disease and other dementias.

Can a brain scan show memory loss?

A UCLA-led study has found that MRI scans can help doctors distinguish whether a person’s memory loss is being caused by Alzheimer’s disease or by traumatic brain injury. The study, which also involved researchers at Washington University in St.

How does peanut butter detect Alzheimer’s?
