The Layperson’s Guide to Medications and Vitamins Relating to Dementias and Alzheimer’s Disease

Jun24

This post will be a comprehensive list – in one place – of the prescription medications and vitamins that may be prescribed for our loved ones suffering from dementias and Alzheimer’s Disease.

My main purpose in doing this is so that caregivers, as medical advocates for our loved ones, have the information needed about the common medications and vitamins used to treat the symptoms of these diseases. 

Currently there is a lot of information on the internet about these, but it’s so scattered and oftentimes so clinically-written that it’s impossible to pull it all together and make wise decisions as to accepting or rejecting medication proposals from primary care physicians and psychiatrists.

And the preceding paragraph has some information caregivers need to know, exercise, and require for their loved ones.

First, both a primary care physician and a psychiatrist need to be involved in medical care for our loved ones. One of the first requests that should be made to the primary care physician after a dementias and/or Alzheimer Disease diagnoses should be a referral to a geriatric psychiatrist.

The reason caregivers need to do this is because geriatric psychiatrists specialize in treating elderly patients and they also have access to the latest research in the treatment of the symptoms of dementias and Alzheimer’s Disease.

Primary care physicians are not specialists. This includes internists. They know a little bit about a lot of things, which is exactly what they were trained for (and that’s not a bad thing), but they don’t have the time nor the resources to be experts in any one thing.

Therefore, a geriatric psychiatrist is an absolute necessity to ensure our loved ones get the best care possible to treat the symptoms of these diseases.

Second, you have the right to refuse medication. For example, one of the medications that Mom’s primary care physician wanted to give her as the Lewy Body dementia symptoms worsened was Abilify. No doubt you’ve all seen the commercials touting Abilify as a “booster” for use with anti-depressants to relieve chronic depression.

This is an “off-label” use of the drug. So is prescribing it for our loved ones with dementias and Alzheimer’s Disease (a lot of the mood and psychosis-managing drugs prescribed for people suffering from dementias and Alzheimer’s Disease are “off-label” uses of those drugs).

I did the homework on it before I filled the prescription. Ability was created to treat schizophrenia. That would have probably been okay, but then I saw the warning that “ABILIFY (aripiprazole) is not approved for the treatment of people with dementia-related psychosis.”

In addition, by then I knew Mom also had Lewy Body dementia in addition to vascular dementia and Alzheimer’s Disease and I knew about the increased neuroleptic sensitivity associated with Lewy Body dementia, so I didn’t fill the prescription.

Prescriptions Dementia Alzheimer's DiseaseThe first category of prescription medications is the cognitive enhancers. These drugs are designed to maintain mental health and may improve memory, awareness and the ability of our loved ones to go about their daily activities by boosting the function of existing neurotransmitters involved in memory and judgment in the brain. They will not reverse nor stop the neurological course of the diseases. They are:

  • Aricept – Approved for all stages of dementias and Alzheimer’s Disease, but most effective in mild to moderate stages
  • Razadyne – Mild to moderate stages of dementias and Alzheimer’s Disease
  • Excelon – Mild to moderate stages of dementias and Alzheimer’s Disease
  • Namenda – Moderate to severe stages of dementias and Alzheimer’s Disease

The second category of prescription medications treats the mood and psychosis symptoms of dementias and Alzheimer’s Disease.

These medications need to be closely monitored and carefully dosed.

The optimal result of these medications is mood stabilization and no psychosis. If your loved ones are “knocked out” by this category of medications, the doses are too high. If your loved ones are “out of control,” the doses are too low. This is another reason you want a psychiatrist involved.

There are many possible combinations of this category of drugs. All the anti-psychotic drugs have possible side effects and extreme caution should be exercised, because of the high sensitivity to neuroleptics,  in using these with our loved ones with Lewy Body dementia. Some of the most commonly-used medications are:

  • SeroquelXR – anti-psychotic (possible side effects of neuroleptic sensitivity and tardive dyskinesia in Lewy Body dementia)
  • Citalopram – anti-depressant
  • Clonazepam – anti-anxiety

Anti-anxiety medications seem to be the most frequently mismanaged in this category of drugs. My advice is to advocate with our loved ones’ psychiatrists for low dosages and have them prescribe it to be taken as-needed instead of as part of the daily medication regimen.

The medication, Halcyon, by the way, should be avoided at all costs in people suffering from dementias and Alzheimer’s Disease. It really wreaks havoc and it has a very long half-life! The most likely place this would be given is during hospitalizations, so be sure to let all the hospital staff you come in contact with know that our loved ones should not be given Halcyon for anxiety and/or sleep.

vitamins for dementia and Alzheimer's DiseaseVitamin supplements may be added to address some of the functioning difficulties brought on by dementias and Alzheimer’s Disease. In my personal experience, I really don’t believe they’re all that effective after the fact of diagnosis. However, we all should make sure we have plenty of this in our own diets now to protect ourselves.

The most common are:

  • Folic acid – helps memory and mental processing speed
  • Vitamin D3 – protects the brain by controlling neurotransmitters and clearing amyloid plaques (found in Alzheimer’s Disease)
  • Vitamin C – protects cells from the effects of free radicals
  • Melatonin – facilitates sleep

Please be careful to work with your loved one’s primary care physician on vitamin supplementation. In many instances, these brain diseases are not the only health issues our loved ones are dealing with and some of the vitamins that might address dementia and Alzheimer’s Disease symptoms could negatively interact with other prescription medication for other health problems.

Our job as loving caregivers is to give the best care we are able to our loved ones, advocating for them, protecting them, making sure that everything that is being done is in their best interests.

We are there because we love them.

All the other participants in the caregiving journey are there for other reasons and those reasons may, intentionally or unintentionally, not consider what is best for our loved ones.

So it’s our job to make sure that we are the gatekeepers to the best care we are able to provide for the people we love. It’s a big responsibility, but, in my opinion, there is no greater gift we can give or be given in this life than to do this.

The Layperson’s Guide to Alzheimer’s Disease

Jun19

Today’s post will provide an overview look at Alzheimer’s Disease. As I’ve stated before, Alzheimer’s Disease is a specific type of brain deterioration disease (dementia) that differs from other dementias.

While Alzheimer’s Disease is a type of dementia, not all dementias are Alzheimer’s Disease. “Alzheimer’s Disease” has become the catch-phrase for all neurological degeneration among the general population and that imprecision leads to a lack of understanding of the complexities of these diseases, especially when several types of dementia are present concurrently.

 

Dementias affect specific areas of the internal structure of the brain and are caused by specific abnormal occurrences within those areas. We’ve looked at vascular (multi-infarct) dementia, which is a result of small vessel ischemia within the blood vessels in the brain, and Lewy Body dementia, which occurs when abnormal proteins are deposited in the cortex of the brain.

Plaques and Tangles in Alzheimer's DiseaseAlzheimer’s Disease affects the whole brain, essentially eroding and diminishing, through the resulting atrophy, the whole structure of the brain. The two crucial components in Alzheimer’s Disease are the overabundant presence of plaques (beta-amyloid protein deposit fragments that accumulate in the spaces between neurons) and tangles (twisted fibers of disintegrating tau proteins that accumulate within neurons). Watch this short video to see how these plaques and tangles form and how they lead to neuron death.

While plaques and tangles, which lead to neuron death (the nerve cells get deprived of what they need to survive and be healthy), are part of the aging process, in our loved ones with Alzheimer’s Disease, there are so many of them that the brain slowly dies from the inside out.

Healthy Brain vs Alzheimer's Disease Brain

It is clear from the picture above exactly why Alzheimer’s Disease is a systemic disease, because all areas of the brain are eventually impacted.

However, as Alzheimer’s Disease begins, the first area of the brain affected is the temporal lobe, which is, in part, responsiblelobes of brain for long and short-term memory, and persistent short-term memory loss is usually one of the first symptoms of Alzheimer’s Disease to appear.

The second area of the brain to be affected is generally the frontal lobe, which handles information processing and decision-making. The last part of the brain to be affected is usually the parietal lobe, which is the area of the brain responsible for language and speech.

Alzheimer’s Disease has distinct stages in which symptoms materialize. The stages are (this lists the three main stages, but there is also a more comprehensive seven-stage breakdown, known as the Global Deterioration Scale or the Reisberg Scale):

  • Stage 1 – Mild – Recurring short-term memory loss, especially of recent conversations and events. Repetitive questions and some trouble with expressing and understanding language. Possible mild coordination problems with writing and using objects. May have mood swings. Need reminders for some daily activities, and may begin have difficulty driving.
  • Stage 2 – Moderate/Middle – Problems are evident. Continual memory loss, which may include forgetting personal history and the inability to recognize friends and family. Rambling speech. Unusual reasoning. More confusion about current events, time, and place. Tends to get lost in familiar settings. Experiences sleep issues (including sundowning). More pervasive changes in mood and behavior, especially when experiencing stress and change. May experience delusions, aggression, and uninhibited behavior. Mobility and coordination may be affected. Need set structure, reminders, and assistance with daily living.
  • Stage 3 – Severe/Late – Confused about past and present. Loses all ability to remember, communicate, or process information. Generally incapacitated with severe to total loss of verbal skills. Unable to care for self. Often features urinary and bowel incontinence. Can exhibit extreme mood disturbances, extreme behavior, and delirium. Problems with swallowing occur in this stage as well.

It’s important to remember that not all our loved ones with Alzheimer’s Disease – especially if there are other dementias present – will go through every aspect of each stage nor through all the stages before they die. That’s one of the real difficulties with “mixed-dementia” diagnoses, as these are called, because it’s difficult to tell which brain disease is causing which problems and that makes them more difficult to manage symptom-wise.

The medications generally prescribed for Alzheimer’s Disease are Aricept (mild to moderate stages), Namenda (moderate stage), and Excelon (mild to moderate). All three of these medications are cognitive enhancers. It’s not unusual to have more than one of these medications prescribed at a time.

I will talk specifically about sleep disturbances in dementias and Alzheimer’s Disease, including sundowning, in another post, but I will caution all caregivers to stay away from both non-prescription sleep medications like Tylenol PM, Advil PM, and ZZZQuil and prescription sleep medications like Lunesta and Ambien (all of these can actually make the symptoms worse and definitely make injury and/or death from a fall more likely).

Melatonin is naturally-occurring sleep hormone in humans. As people age, there is less melatonin produced. That’s why, in general, most older people who have never had sleep disorders eventually and gradually sleep less than their younger counterparts. However, the brain damage that dementias and Alzheimer’s Disease cause exacerbates this lack of melatonin. 

So, it’s worth it to try a therapeutic dose (up to 20 mg per night is considered to be safe) of Melatonin. It is available over-the-counter at both brick-and-mortar and online drug stores.

Start with a 3 mg dose and add slowly. With my mom, a 5 mg dose provided enough for her to sleep as best as she could through the night. Do not overdose because this will disrupt the circadian rhythm further by producing late sleeping and grogginess during the day.

Usually our loved ones with dementia and/or Alzheimer’s Disease, even though these diseases are fatal (when the brain’s dead, you’re dead), don’t die from them specifically.

They die either from a concurrent health problem (in my mom’s case, it was congestive heart failure which lead to a major heart attack, a minimal recovery, and then her death twelve days later) or from complications that arise from the brain degeneration caused by the dementias and/or Alzheimer’s Disease.

The two most common causes of death in Alzheimer’s Disease are pneumonia (the brain controls swallowing, and once that becomes compromised, aspiration of food into the lungs is likely and leads to an infection) and fatal trauma to the head from falls.

The Layperson’s Guide to Vascular Dementia, Multi-Infarct Dementia, Small Vessel Ischemia, and TIA’s

Jun13

There are many kinds of dementia. In the next few posts, we’ll take a look at a few of them, along with Alzheimer’s Disease, which is a distinct neurological diagnosis from dementias.

Before we start, it is important to note that our loved ones can suffer from only Alzheimer’s Disease or only one kind of dementia. Or they may suffer from Alzheimer’s Disease and multiple kinds of dementia. That distinction is important to loving caregiving, which includes medical advocacy for our loved ones, because each brain disease is distinct, affects the brain differently, and has specific characteristics and symptoms and treatment.

I will admit here that one of my pet peeves while caring for my mom was hearing some people who have no real knowledge of these diseases lump everyone who suffers from them under Alzheimer’s Disease and giving advice on how to deal with that, not realizing the complexity of the situation posed by the presence of both dementias and Alzheimer’s Disease.

So, for non-caregivers or those who are unfamiliar and inexperienced with these diseases who may be reading this, please don’t assume because you’ve seen or read The Notebook that you’re an expert on the subject and please don’t offer medical diagnoses and advice.

The best gift you can give is to just listen and offer non-medical support. Most caregivers get so deep into the details and all the aspects of these diseases because they need to be able to take care of their loved ones in so many ways that if there were such a thing as a non-M.D. expert on them, most caregivers would qualify.

This post will discuss vascular (multi-infarct) dementia. The cause of this dementia is small vessel ischemia in the brain, which presents itself as chronic transient ischemic attacks (TIA’s). TIA’s are sometimes also referred to as mini-strokes.

TIA’s can occur when the small vessels in the brain get temporarily blocked, cutting off the blood supply and oxygen to that part of the brain. The cumulative affect of these is what causes the damage that is present in vascular dementia. Multi-infarct dementia just means that there are many areas in the brain where this vascular damage has occurred and accrued.

Although high blood pressure is a culprit, high levels of stress and a history of migraines are also players in these kind of TIA’s.

In my mom’s case, all three were factors, but high levels of stress were what brought on the majority of her TIA’s. I suspect she started having these as a small child, because there were times that she just couldn’t remember what happened in a specific instance but she’d referred to it as “blacking out.”

She never lost consciousness with them that I witnessed, but she used the same expression to describes times when we kids were all babies and she was under a lot of stress and she couldn’t remember certain instances of things.

Her TIA’s were common as we grew up, and although we never got over the shock of the suddenness of symptoms and the helplessness we had to do anything about it, we all got pretty good at taking care of her when she had one, and that lasted for Daddy until his death, and for me into adulthood until Mama’s death.

Her TIA’s always presented the same way. They were sudden. Her face would lose all color and her lips would get very pursed as she seemed to salivate more. There was a sort of paralysis except for her right hand. She would start rubbing her thumb across the first two fingers and that would last until the episode was over. I suspect there was a sense of unreality associated with the TIA, so the feeling of her fingers rubbing together was the only reality for her in those episodes.

I’d always hold Mama’s left hand and kind of stroke it so she knew I was there and she wasn’t alone. When the TIA was over, she’d immediately try to talk and everything came out totally garbled. That would last about thirty minutes and then she’d be okay.

And she never remembered them happening. I remember the first time I was giving her medical history as her POA at an ER (and this was way before the dementias and Alzheimer’s Disease) and I named TIA’s as part of her medical history and she disagreed with me and said she didn’t remember ever having those. I laughed at the time and told her that not remembering them was part of the symptom of having them.

small-vessel-ischemia-brain-mriOver time, though, as small vessel ischemia recurs, eventually clusters of damage occur in the brain. This disrupts the normal neurological pathways of how information is learned and communicated. One of the most clear indicators of vascular dementia is difficulty in communication. One of these difficulties is misnaming things.

For example, the brain knows that a pencil is a pencil. Someone suffering from vascular dementia knows a pencil is a pencil. But because of the damaged pathways, there is often a break in the connection between knowledge and speech, so someone with vascular dementia is just as likely to call a pencil an apple.

Another clear indicator of vascular dementia is slower processing time. A brain with vascular dementia will fight to reroute stored information to speech. However, because of the extensive damage, it has to take a much more convoluted and lengthier route to do that conversion.

A third clear indicator of vascular dementia is that it occurs in sudden, steep steps of decline (brought on by recurrent TIA’s and new clustered areas of damage in the brain). These can occur in a very short period of time, as they did in my mom’s case.

In addition to these definitive indicators, vascular dementia also has features in common with other dementias, including difficulty learning anything new, cognitive impairment, problems with short-term memory, extreme emotional swings, and confusion.

There are no specific treatments for vascular dementia. Unlike any other organ in the body, once the brain has sustained damage, that damage is permanent.

However, there are medications that can address the symptoms of vascular dementia. The two most likely to help are cognitive enhancers: Excelon (although this comes in oral form, the 24-hour patch is best, if there’s no allergic reaction, to get the continual effect of medication that comes in a starting dose of 4.6 mg, a stabilizing dose of 9.5 mg, and a high dose at 13.3 mg)  and Namenda (given in 5 mg increments, two to three times a day).

When I discuss the medications in later posts, I will give some practical experience and advice on these two medications, especially with regard to Medicare, the “donut hole,” and working with your loved one’s psychiatrist to get the medication at either no charge or a reduced rate during the “donut hole” period. Both of these are patented, so there’s no cheaper generic version. And paying full price for them will break the bank.

In the next post, we’ll take a look at Lewy Body dementia: what is is, how it’s diagnosed, what it looks like, and effective treatments for the symptoms.
