What it takes to get a dementia diagnosis
So many families ask “how is dementia diagnosed?”
If you’re concerned that your older adult might have Alzheimer’s or dementia, it’s important to know how to get an accurate diagnosis.
This is essential because dementia-like symptoms could be caused by other reversible health conditions. An accurate diagnosis is needed for proper treatment.
Knowing what a doctor should evaluate helps you protect your older adult in case their doctor jumps to a diagnosis without going through the full exam and tests.
She describes the basic diagnostic tests, what types of information are needed, and how long the process takes.

5 key symptoms of dementia
Dr. Kernisan describes the 5 issues that people with dementia typically experience:
- Difficulty with one or more types of mental function, like learning, memory, language, judgement
- Problems that are a change compared to the person’s usual abilities
- Problems that make it difficult for them to manage everyday life responsibilities, like work or family
- Problems that aren’t caused by another mental disorder, like depression
5 steps doctors take to diagnose dementia
Doctors typically go through 5 areas of evaluation to figure out whether or not someone has dementia. The doctor needs to check each area and document what they find.
1. Difficulty with mental functions
This is usually evaluated with a combination of an office-based cognitive test and finding out about real-world problems by talking with their patient and people close to them.
2. Decline from previous level of ability
This can be more difficult for a doctor to determine, so they need to talk with people who know the patient well to understand their previous abilities versus what they can do today.
For example, if a former accountant can no longer do basic math, that’s a decline from their previous ability.
3. Impairment of daily life function
This can also be tough for doctors to evaluate on their own.
So, the doctor will ask people close to their patient about what types of help the person is getting in their daily life and what problems family members have noticed.
4. Reversible causes of cognitive impairment
Certain conditions can cause temporary dementia-like symptoms.
Other medical problems that interfere with thinking skills include medication side effects, thyroid problems, electrolyte imbalances, B12 deficiency, substance abuse, and other treatable health conditions.
5. Other mental disorders
Depression is a common mental health issue for seniors and can sometimes be confused with dementia symptoms.
And sometimes, they could have depression and dementia at the same time.
It’s also important to consider the person’s mental health history. Paranoia or delusions could be related to mental health conditions like schizophrenia.
Dementia cannot be diagnosed in a single visit
The 5 areas a doctor must evaluate to give a proper dementia diagnosis are complex and require a lot of information gathering and lab tests.
So it’s highly unlikely that any doctor could make an accurate diagnosis in one office visit.
What to do if a doctor jumps to a diagnosis in a single visit
Unfortunately, some doctors do jump quickly to a dementia diagnosis in only one visit. Even worse, they don’t properly document what led to their decision.
If this happens, you may want to seek a second opinion from a doctor who is willing and able to do more thorough evaluation and testing.
Yes, there is a chance that your older adults symptoms could mean that they have dementia.
But what if their dementia-like symptoms are caused by other reversible health conditions?
That’s why an accurate diagnosis is essential for proper treatment.
