An Often Misdiagnosed Dementia

Lewey body dementia is an often misdiagnosed dementia.

Many people had never heard of Lewy body dementia until it was reported in 2014 that this was the disease that afflicted Robin Williams. While Lewy body dementia and Alzheimer’s disease are the two most common types of dementia, those who have Lewy body dementia are often misdiagnosed as having Alzheimer’s disease or depression. As a result, they do not get the treatment and support they need.

Considerable’s recent article entitled “The second most common type of dementia often goes unrecognized” reports that in one study, nearly 70% of people diagnosed with Lewy body dementia visited three consultants before receiving the diagnosis. For 33% of people with the disease, the dementia was misdiagnosed and getting the correct diagnosis took over two years.

There are two different conditions associated with Lewy body dementia: dementia with Lewy bodies and Parkinson’s disease dementia. In dementia with Lewy bodies, problems with memory and thinking occur simultaneously with problems involving movement, like those associated with Parkinson’s disease. In Parkinson’s disease dementia, a person who has had movement problems resembling Parkinson’s disease for several years, then develops difficulties with memory and thinking.

In addition to memory, thinking, and movement problems, symptoms of Lewy body dementia include issues with alertness and concentration, hallucinations and paranoia, acting out dreams during sleep, low blood pressure when standing, daytime sleepiness and depression.

Because the symptoms of Lewy body dementia often resemble other conditions, research reveals that the first diagnosis is commonly incorrect. For example, in one study 26% of people who had Lewy body dementia were misdiagnosed as having Alzheimer’s disease, and 24% were determined to have a psychiatric diagnosis like depression.

We saw this first hand at our firm when a family member was suffering with this kind of dementia. It went undiagnosed until it was too late to treat it properly. We feel it’s important to get the word out to family members who might think their loved one is suffering from depression, Parkinson’s disease, or another kind of dementia.

Failure to properly diagnose a person with Lewy body dementia can result in delay in treatment specifically targeted for that condition. Also, with the correct diagnosis, patients and families can seek out resources, such as the Lewy Body Dementia Association, an organization dedicated to helping people living with this disease. This group provides education on Lewy body dementia, helps patients and families know what to expect, connects patients and families to support and resources and helps them find research opportunities.

Some Common Drugs May Increase Risk of Dementia

Some common drugs may cause increased risk of dementia.
Some common drugs may cause increased risk of dementia.

Research conducted in 2019 has strengthened the connection between the risk of dementia and a common class of drugs used to treat a variety of symptoms.

Anticholinergics are a type of medication that blocks the action of acetylcholine. That’s a chemical messenger (or “neurotransmitter”) in the brain that help coordinate breathing, digestion, urination and other functions.

Anticholinergics can treat a variety of ailments, including urinary incontinence.

Considerable’s recent article entitled “These common prescription drugs could boost your risk of dementia” reports that anticholinergics include a roster of drugs for depression (such as Paxil), psychosis (such as Thorazine), Parkinson’s disease (such as Cogentin) and bladder disorders (such as Ditropan).

The 2019 study found a nearly 50% increase in chances of dementia in those people who received more than 1,095 daily doses of these drugs in a 10-year period.

The research was published in JAMA Internal Medicine.

The study, sponsored by the University of Nottingham, monitored 284,343 patients age 55 and older between 2004 and 2016. The researchers examined the total standardized daily doses (TSDDs) of anticholinergic drugs during that time period.

The researchers said that this was the equivalent to a senior taking a strong anticholinergic medication daily for at least three years.

Researchers looked at each person’s anticholinergic exposure and found the most frequently prescribed anticholinergic drugs were antidepressants, drugs to treat vertigo, motion sickness or vomiting and an overactive bladder.

The researchers at the University of Nottingham discovered that some other anticholinergic antihistamines and gastrointestinal drugs failed to correspond to a higher incidence of dementia.

The UK study shows a correlation between these specific anticholinergic drugs and increased chances of dementia. However, the researchers cautioned that seniors shouldn’t stop taking any medications without talking with their doctor.

The Symptoms of Early-Onset Alzheimer’s Disease

Here are 7 key symptoms of early-onset Alzheimer’s Disease.

Many people face cognitive challenges as they age, such as memory loss.  Some suffer from dementia or Alzheimer’s disease, and some even have early-onset Alzheimer’s.  Considerable’s recent article entitled “7 surprising early signs of Alzheimer’s” provides us with some signs of early-onset Alzheimer’s disease.

Theft or other law-breaking. Any behavioral change as people age is of concern, but this can be a sign of Frontotemporal Dementia (FTD), another progressively damaging, age-related brain disorder. FTD usually hits adults aged 45-65. People’s executive function—their ability to make decisions—can be impacted by FTD, which may explain why they become unable to discern right from wrong.  I have had clients in the past discover this condition after an arrest or fine lead to a medical exam.

Frequent falls. A study of 125 older adults asked them to record how frequently in an eight-month period that they fell or tripped. Researchers examined the brain scans of those who fell most frequently and saw a correlation between falls and early-onset Alzheimer’s Disease.

Forgetting an object’s function. We all forget where we put the keys. However, if you can’t remember what a key is for, or where dirty dishes are supposed to go, then it may be the first signs of Alzheimer’s Disease or dementia.

Inappropriate diet. Prior to the onset of Alzheimer’s, patients typically to eat more (roughly 500 calories more a day) than their aging counterparts but they still tend to lose weight. Doctors think this is a metabolic change. Some elderly actually eat inanimate objects prior to their diagnosis, but researchers don’t know the reason. Because Alzheimer’s and dementia affect the brain’s memory, it may be because their brain receives hunger signals but is unable to discern how to react to them. Some patients eat paper or other inedible objects.

Inability to recognize sarcasm. If you fail to recognize sarcasm or take it very literally and seriously, it may be a sign of atrophy in your brain. A study at the University of California – San Francisco found that Alzheimer’s patients and those with Frontotemporal Disease were among those who couldn’t recognize sarcasm in face-to-face encounters. The brain’s posterior hippocampus is impacted, which is where short-term memory is stored and where a person sorts out such things, like sarcasm.

Depression. If someone has never suffered from clinical depression but develops it after age 50, it could be an early sign of Alzheimer’s. It doesn’t mean if you’re diagnosed with depression in older age that you will develop Alzheimer’s or other cognitive decline. However, get treatment soon because some researchers believe that hormones released in the depressed brain may damage certain areas of it, leading to the development of Alzheimer’s or other dementia.

Unfocused Staring. Alzheimer’s Disease is a change in cognitive and executive functioning in the brain. This means that your ability to recall facts, memories and information is compromised, as well as the ability to make decisions. The brain becomes unfocused and staring in a detached way may be an early sign of so-called “tangles” in your brain.

If you are interest in this topic, I also wrote a blog on early onset dementia more generally which you can find here.  https://galligan-law.com/what-do-we-know-about-early-onset-dementia/

These symptoms may be signs of early-onset Alzheimer’s Disease, or they may be the signs of other underlying issues. If you or any of your loved ones have any of these signs, consult your doctor.  This may be a sign of something else but talk to your doctor to be safe.
