Nobody Has Aids I Dont Want to Hear That Word Again!!
"Doctor, do you diagnose dementia? Because I need someone who can diagnose dementia."
A man asked me this question recently. He explained that his 86 yr-old male parent, who lived in the Bay Expanse, had recently been widowed. Since and so the father had sold his long-time home rather speedily, and was hardly returning his son'due south calls.
The son wanted to know if I could brand a housecall. Specifically, he wanted to know if his father has dementia, such as Alzheimer's disease.
This is a reasonable business organization to have, given the circumstances.
However, information technology's not very likely that I — or any clinician — volition be able to definitely diagnose dementia based a unmarried in-person visit.
Only I get this kind of request fairly ofttimes. So in this mail service I desire to share what I often discover myself explaining to families: the basics of clinical dementia diagnosis, what kind of data I'll need to obtain, and how long the process tin take.
Now, note that this mail service is not about the comprehensive arroyo used in multi-disciplinary memory clinics. Those clinics have extra fourth dimension and staff, and are designed to provide an extra-detailed evaluation. This is peculiarly useful for unusual cases, such as cognitive problems in people who are relatively young.
Instead, in this post I'll exist describing the pragmatic approach that I apply in my clinical do. It is adapted to real-globe constraints, pregnant it can be used in a primary care setting. (Although like many aspects of geriatrics, it'south challenging to fit this into a fifteen infinitesimal visit.)
Does this older person have dementia, such every bit Alzheimer's disease? To sympathise how I go near answering the question, permit's get-go past reviewing the basics of what information technology ways to accept dementia.
5 Key Features of Dementia
A person having dementia ways that all five of the following statements are true:
- A person is having difficulty with one or more types of mental office. Although it's common for memory to be affected, other parts of thinking function can be impaired. The 2013 DSM-v manual lists these half dozen types of cognitive function to consider: learning and memory, language, executive part, complex attention, perceptual-motor function, social cognition.
- The difficulties are a decline from the person's prior level of ability. These can't exist lifelong problems with reading or math or even social graces. These bug should stand for a modify, compared to the person's usual abilities as an adult.
- The problems are bad enough to impair daily life role. It'south non enough for a person to have an abnormal result on an office-based cognitive test. The problems likewise have to exist substantial enough to affect how the person manages usual life, such every bit work and family responsibilities.
- The problems are not due to a reversible condition, such as delirium, or another reversible illness. Common conditions that tin cause — or worsen — dementia-similar symptoms include hypothyroidism, depression, and medication side-effects.
- The problems aren't better accounted for by another mental disorder, such as depression or schizophrenia.
Dementia — at present technically known as "major neurocognitive disorder" — is a syndrome, or "umbrella" term; it's not considered a specific affliction. Rather, the term dementia refers to this drove of features, which is caused by some form of underlying damage or deterioration of the brain.
Alzheimer's affliction is the well-nigh mutual underlying cause of dementia. Vascular dementia (damage from strokes, which tin can be quite pocket-sized) is also mutual, every bit is having two or more than underlying causes for dementia. For more on conditions that can cause dementia, run across here.
What Doctors Need to Exercise To Diagnose Dementia
Now that nosotros reviewed the five cardinal features of dementia, allow's talk about how I — or another doctor — might go nigh checking for these.
Basically, for each feature, the md needs to evaluate, and document what she finds.
one. Difficulty with mental functions. To evaluate this, information technology'due south best to combine an office-based cognitive exam with documentation of real-world problems, as reported by the patient and by knowledgeable observers (east.g family, friends, assisted-living facility staff, etc.)
For cognitive testing, I generally use the Mini-Cog, or the MOCA. The MOCA provides more information only it takes more fourth dimension, and many seniors are either unwilling or unable to get through the whole test.
Completing part-based tests is important considering it's a standardized way to document cognitive abilities. But the results don't tell the doc much nigh what's going on in the person's actual life.
And then I always ask patients to tell me if they've noticed any trouble with retention or thinking. I as well try to become data from family unit members almost any of the 8 behaviors that are common in Alzheimer's. Lastly, I make notation of whether at that place seem to be any bug 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 hard for me to observe on my own during a single visit. To document a decline in abilities, a doctor tin interview other people, and/or certificate that she's reviewed previous cognitive assessments. I have likewise occasionally documented that a patient is currently unable to correctly perform a cognitive chore that is related to her career or pedagogy history. For instance, if a old auditor can no longer manage basic arithmetic, we might assume this reflects a decline from previous abilities.
three. Damage of daily life function.This is another characteristic that can be tricky to detect during a single visit, unless the patient is very impaired. I usually outset by finding out what kinds of ADLs and IADLs aid the person is getting, and what kinds of problems have 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 as dementia develops, these are ofttimes the life tasks that people struggle with showtime.
In some cases — commonly very early dementia — it can be quite difficult to decide whether a person'due south struggles have become enough to qualify as "impairment of daily life function." If someone isn't taking his medication, is that just regular forgetfulness? Clashing feelings about the medication? Or actual impairment due to encephalon changes? If I'thou non certain and so I may document that the situation seems to exist borderline, when it comes to harm of daily life function.
4. Checking for reversible causes of cognitive impairment. I mentally divide this step into two parts. First, I consider the possibility of delirium, a very mutual state of worse-than-usual mental function that's often brought on by affliction. For instance, I've noticed that older people are oftentimes mentally assessed during or after a hospitalization. Simply that's non a skilful time to try to definitely diagnose dementia, considering many seniors develop delirium when they are ill, and it can accept weeks or even months to render to their previous level of mental function.
(My approach to considering dementia in seniors who are dislocated during or after hospitalization: Make a notation that they may have underlying dementia, and plan to follow-up once the encephalon has had a gamble to recover.)
After considering delirium, I check to see if the patient might take another medical trouble that interferes with thinking skills. Common medical disorders that can bear upon thinking include depression, thyroid problems, electrolyte imbalances, B12 deficiency, and medication side-furnishings. I besides consider the possibility of substance corruption.
Checking for many of these causes of cerebral harm requires laboratory testing, and sometimes additional evaluation.
If I practice 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 problem that's making the thinking worse. But I practice plan to reassess the person's thinking at a later date.
5. Checking for other mental disorders.This step can be a challenge. Low is the about mutual mental health problem that makes dementia diagnosis difficult. This is because depression is fairly common in seniors, and it tin cause symptoms similar to those of dementia (such every bit aloofness, and poor attending). We besides know that it's quite common for people to have both dementia and low at the same time.
In many cases, there may exist no piece of cake way to make up one's mind whether an older person'southward symptoms are depression, early dementia, or both. So sometimes we stop up trying a course of depression treatment, and seeing how the symptoms evolve over time.
It's also of import to consider the older person's mental health history. Paranoia and delusions are quite common in early dementia, only could be related to a mental wellness condition associated with psychosis, such as schizophrenia.
Tin Dementia Be Diagnosed During a Single Visit?
So tin can dementia be diagnosed during a single visit? As y'all can see from above, it depends on how much information is easily available at that visit. It as well depends on the symptoms and circumstances of the older adult being evaluated.
Retentiveness clinics are more likely to provide a diagnosis during the visit, or shortly afterwards. That'south because they usually request a lot of relevant medical information ahead of time, send the patient for tests if needed, and interview the patient and informers extensively during the visit.
But in the master intendance setting, and in my own geriatric consultations, I notice that clinicians need more than ane visit to diagnose dementia or probable dementia. That's because we usually demand to order tests, asking past medical records for review, and assemble more information from the people who know the senior being evaluated. Information technology'due south a bit like a detective'southward investigation!
Tin can Dementia be Inappropriately Diagnosed in a Unmarried Visit?
Sadly, yeah. Although it's mutual for doctors to never diagnose dementia at all in people who have it, I accept likewise come across several instances of decorated doctors rattling off a dementia diagnosis, without fairly documenting how they reached this conclusion. (It's likewise common for them to hardly document anything in terms of the senior'southward cerebral state, other than "confused, didn't know date.")
Now, often these doctors are right. Dementia becomes mutual as people historic period, so if a family complains of memory problems and paranoia in an 89 year erstwhile, chances are quite loftier (at least 60%, according to UpToDate) that the older person has dementia.
But sometimes it's not. Sometimes it's slowly resolving delirium along with a brain-clouding medication. Sometimes information technology's depression.
Information technology is a major matter to diagnose someone with dementia. And then although information technology's not possible for an average md to evaluate with equally much particular as the memory clinic does, it'southward important to document consideration of the 5 essential features as listed to a higher place.
If You're Worried About Possible Dementia
Let's say you're like the man I spoke to recently, and you're worried that an older parent might have dementia. Yous're planning to have a doctor appraise your parent. Hither's how yous can aid the process along:
- Obtain copies of your parent'southward medical information, so you can bring them to the dementia evaluation visit. The most useful information to bring is laboratory results and any imaging of the brain, such as Cat scans or MRIs. See this postal service for a longer list of medical information that is very helpful to bring to a new md.
- Write down worrisome behaviors and issues, and bring this documentation to the visit. You lot tin can commencement with this list of 8 behaviors to track if you're concerned about Alzheimer'south.
- Consider who else might know how your parent has been doing and behaving recently: other family members? Close friends? Staff at the assisted-living facility? Ask them to share their observations with you and jot down what they tell you. Share these notes, along with the names of the informants, with your parent'south medico.
- Be prepared to explain how your parent'due south abilities have changed from before.
- Be prepared to explain how your parent is struggling to manage daily life tasks, such every bit work, business firm chores, shopping, driving, or any other ADLs and IADLs.
- Bring information about whatever recent hospitalizations or illnesses.
- Bring information near any history of low, depressive symptoms, or other mental affliction history.
By understanding what it takes to diagnose dementia, and by doing a little advance preparation when possible, you will meliorate your chances of getting the evaluation y'all need, in a timely fashion.
