Ecky Enjoys Bringing Her Hands to Her Mouth Over and Over Again

"Doctor, do you lot diagnose dementia? Because I need someone who can diagnose dementia."

A human asked me this question recently. He explained that his 86 year-old father, who lived in the Bay Expanse, had recently been widowed. Since and then the father had sold his long-fourth dimension home rather quickly, and was hardly returning his son'due south calls.

The son wanted to know if I could make a housecall. Specifically, he wanted to know if his father has dementia, such equally Alzheimer's disease.

This is a reasonable business to have, given the circumstances.

However, it's not very likely that I — or any clinician — will be able to definitely diagnose dementia based a single in-person visit.

But I get this kind of asking fairly oftentimes. Then in this mail I desire to share what I often find myself explaining to families: the basics of clinical dementia diagnosis, what kind of information I'll need to obtain, and how long the procedure can take.

Now, note that this post is non nearly the comprehensive approach used in multi-disciplinary memory clinics. Those clinics have extra time and staff, and are designed to provide an actress-detailed evaluation. This is especially useful for unusual cases, such as cognitive problems in people who are relatively immature.

Instead, in this mail service I'll be describing the pragmatic arroyo that I use in my clinical practice. It is adapted to existent-world constraints, meaning it can exist used in a primary care setting. (Although similar many aspects of geriatrics, it's challenging to fit this into a xv minute visit.)

Does this older person accept dementia, such as Alzheimer's disease? To understand how I go near answering the question, let's start past reviewing the nuts of what it means to accept dementia.

five Central Features of Dementia

A person having dementia means that all five of the post-obit statements are true:

• A person is having difficulty with one or more types of mental role. Although it's mutual for retention to be affected, other parts of thinking function can be impaired. The 2013 DSM-v manual lists these half-dozen types of cognitive part to consider: learning and retentivity, language, executive role, complex attention, perceptual-motor role, social noesis.

• The difficulties are a turn down from the person's prior level of ability. These can't be lifelong problems with reading or math or even social graces. These issues should correspond a alter, compared to the person's usual abilities as an adult.

• The problems are bad plenty to impair daily life office. It's not enough for a person to have an abnormal outcome on an role-based cerebral test.  The issues also have to exist substantial enough to affect how the person manages usual life, such every bit piece of work and family responsibilities.

• The problems are non due to a reversible condition, such as delirium, or some other reversible affliction. Common weather condition that can cause — or worsen — dementia-like symptoms include hypothyroidism, depression, and medication side-effects.

• The problems aren't meliorate accounted for by some other mental disorder, such as depression or schizophrenia.

Dementia — at present technically known equally "major neurocognitive disorder" — is a syndrome, or "umbrella" term; it's not considered a specific disease. Rather, the term dementia refers to this collection of features, which is acquired by some form of underlying impairment or deterioration of the brain.

Alzheimer's affliction is the most common underlying cause of dementia. Vascular dementia (harm from strokes, which can be quite pocket-size) is likewise common, as is having two or more underlying causes for dementia. For more on weather condition that tin can cause dementia, see here.

What Doctors Demand to Do To Diagnose Dementia

Now that we reviewed the five fundamental features of dementia, permit'due south talk about how I — or another medico — might become about checking for these.

Basically, for each feature, the doctor needs to evaluate, and document what she finds.

one. Difficulty with mental functions. To evaluate this, it's all-time to combine an part-based cerebral exam with documentation of real-world problems, as reported by the patient and past knowledgeable observers (eastward.thou family unit, friends, assisted-living facility staff, etc.)

For cognitive testing, I generally apply the Mini-Cog, or the MOCA. The MOCA provides more information simply it takes more time, and many older adults are either unwilling or unable to go through the whole examination.

Completing role-based tests is important considering it's a standardized way to document cognitive abilities. Simply the results don't tell the doctor much nigh what's going on in the person's actual life.

And so I always ask patients to tell me if they've noticed whatever trouble with retentivity or thinking. I also try to get information from family members about any of the eight behaviors that are mutual in Alzheimer's. Lastly, I brand note of whether there seem to be any problems managing activities of daily living (ADLs) and instrumental activities of daily living (IADLs).

two. Turn down from previous level of ability. This feature can be difficult for me to find on my ain during a single visit. To document a decline in abilities, a doctor can interview other people, and/or document that she'southward reviewed previous cognitive assessments. I accept also occasionally documented that a patient is currently unable to correctly perform a cognitive task that is related to her career or education history. For example, if a one-time accountant tin no longer manage basic arithmetic, it's reasonable to assume this reflects a decline from previous abilities.

3. Damage of daily life function.This is another feature that can be tricky to detect during a single visit, unless the patient is very impaired. I ordinarily start past finding out what kinds of ADLs and IADLs help the person is getting, and what kinds of bug accept been noted. This often means talking to at least a few people who know the patient.

Driving and managing finances require a lot of mental coordination, so every bit dementia develops, these are often the life tasks that people struggle with first.

In some cases — ordinarily very early dementia — information technology can be quite hard to determine whether a person's struggles have become  enough to qualify as "harm of daily life function." If someone isn't taking his medication, is that but regular forgetfulness? Ambivalent feelings virtually the medication? Or actual impairment due to brain changes? If I'm not certain, then I may certificate that the state of affairs seems to be borderline, when it comes to impairment of daily life function.

4. Checking for reversible causes of cognitive impairment. I mentally separate this footstep into two parts. First, I consider the possibility of delirium, a very common state of worse-than-usual mental function that'south often brought on past illness.  For instance, I've noticed that older people are frequently mentally assessed during or after a hospitalization. But that's not a good time to try to definitely diagnose dementia, because many elders develop delirium when they are ill, and information technology can have weeks or even months to render to their previous level of mental office.

(My arroyo to considering dementia in older adults who are confused during or afterward hospitalization: Make a note that they may have underlying dementia, and program to follow-upward once the brain has had a hazard to recover.)

After considering delirium, I check to see if the patient might have some other medical trouble that interferes with thinking skills. Common medical disorders that tin can affect thinking include depression, thyroid problems, electrolyte imbalances, B12 deficiency, and medication side-effects. I also consider the possibility of substance abuse.

Checking for many of these causes of cognitive harm requires laboratory testing, and sometimes additional evaluation.

If I practise suspect delirium or another trouble that might cause cognitive impairment, I don't rule out dementia. That's because it's very common to have dementia along with another trouble that's making the thinking worse. But I do plan to reassess the person'south thinking at a later date.

five. Checking for other mental disorders.This stride tin can be a challenge. Depression is the almost common mental health problem that makes dementia diagnosis hard. This is because low is not uncommon in older adults, and it tin cause symptoms similar to those of dementia (such as apathy, and poor attending). We too know that it's quite mutual for people to have both dementia and depression at the same time.

In many cases, at that place may be no easy manner to decide whether an older person'southward symptoms are low, early dementia, or both. So sometimes we finish upwards trying a course of depression treatment, and seeing how the symptoms evolve over time.

Information technology's as well important to consider the older person's mental health history. Paranoia and delusions are quite mutual in early on dementia, but could be related to a mental health condition associated with psychosis, such equally schizophrenia.

Is it Dementia or Mild Cerebral Impairment?

Sometimes, when an older person is having retentivity bug or other cerebral bug, they cease up diagnosed with "mild cognitive impairment."

Mild cerebral damage (MCI) means that a person's memory or thinking abilities are worse than expected for their age (this should exist confirmed through role-based cognitive testing), but are slap-up enough to impair daily life function.

The initial evaluations for MCI and dementia are basically the same: doctors need to exercise a preliminary office-based cognitive evaluation, ask about ADLs and IADLs, look for potential medical and psychiatric issues that might be affecting brain office, check for medications that affect noesis, and so along.

I explain more about MCI in this article: How to Diagnose & Treat Mild Cognitive Impairment.

Simply remember: in practical terms, if an older person's retentiveness problems have gotten bad enough that he tin can't grocery shop the mode he used to, or she can no longer manage her finances on her ain…those qualify equally harm in daily life function. And so, a diagnosis of "mild cognitive impairment" is probably not appropriate for those cases.

Can Dementia Be Diagnosed During a Single Visit?

So can dementia exist diagnosed during a single visit? Every bit you can see from higher up, information technology depends on how much information is easily available at that visit. It also depends on the symptoms and circumstances of the older developed being evaluated.

Retentiveness clinics are more likely to provide a diagnosis during the visit, or shortly afterward. That's because they normally request a lot of relevant medical information alee of time, transport the patient for tests if needed, and interview the patient and a family member (or other knowledgeable "informant") extensively during the visit.

But in the primary care setting, and in my ain geriatric consultations, I detect that clinicians demand more than one visit to diagnose dementia or probable dementia. That'southward considering we usually need to order tests, request past medical records for review, and gather more data from the people who know the older person beingness evaluated. It'southward a flake like a detective's investigation!

Can Dementia be Inappropriately Diagnosed in a Unmarried Visit?

Sadly, yes. Although it's mutual for doctors to never diagnose dementia at all in people who accept information technology, I have also come beyond several instances of busy doctors rattling off a dementia diagnosis, without adequately documenting how they reached this conclusion. (It's also mutual for them to inappreciably document anything in terms of the older peron's cognitive state, other than "confused, didn't know engagement.")

Now, oftentimes these doctors are right. Dementia becomes common as people age, so if a family complains of memory issues and paranoia in an 89 year sometime, chances are quite high (at to the lowest degree lx%, according to UpToDate) that the older person has dementia.

Merely sometimes it's non. Sometimes it's slowly resolving delirium along with a brain-clouding medication. Sometimes it's low.

It is a major affair to diagnose someone with dementia. And then although it'southward non possible for an average doctor to evaluate as thoroughly equally the retentivity dispensary does, it'southward important to certificate consideration of the 5 essential features of dementia that I listed in a higher place.

If Y'all're Worried About Possible Alzheimer'due south or Dementia

Let's say you're like the human being I spoke to recently, and y'all're worried that an older parent might have dementia. (Remember, most dementia is due to Alzheimer's or a similar underlying brain condition.) You're planning to have a doctor appraise your parent. Here's how you can assistance the process along:

• Obtain copies of your parent's medical information, so you lot tin can bring them to the dementia evaluation visit. The most useful data to bring is laboratory results and whatsoever imaging of the brain, such as CAT scans or MRIs. See this mail for a longer listing of medical information that is very helpful to bring to a new doctor.

• Write downward worrisome behaviors and bug, and bring this documentation to the visit. You can start with this list of 8 behaviors to track if you lot're concerned about Alzheimer'due south.

• Consider who else might know how your parent has been doing and behaving recently: other family members? Shut friends? Staff at the assisted-living facility?  Ask them to share their observations with y'all and jot down what they tell yous. Share these notes, along with the names of the informants, with your parent's dr..

• Be prepared to explain how your parent's abilities have changed from before.

• Exist prepared to explicate how your parent is struggling to manage daily life tasks, such equally work, house chores, shopping, driving, or any other ADLs and IADLs.

• Bring information almost any recent hospitalizations or illnesses.

• Bring information about any history of depression, depressive symptoms, or other mental illness history.

By understanding what it takes to diagnose dementia, and by doing a little advance preparation when possible, you will ameliorate your chances of getting the evaluation you lot need, in a timely fashion.

And if you have an aging parent who is refusing to get evaluated for memory loss or other concerning symptoms: my free online training for families (run into below) covers how to go past this, and includes a nifty PDF summarizing what to say and not say to your parent who may have dementia.
