Would you donate your brain to research?

I imagine that migraine has worn grooves into my brain, creating a map that will help researchers explore the wilderness of migraine. Although I know the changes are not so literal and visible, I’ve talked about donating my brain to migraine research for at least a decade. I want the agony I have endured to be used to further the understanding of migraine. I know my work does that to some extent; I want to do more. I want to impact the science. The American Registry for Migraine Research, which is getting up and running this year, will provide a place to do that. (Not only by donating brain tissue, but donating blood and saliva samples as well as data.)

I was interested in donating my body to science since well before chronic migraine disabled me. Then I started to read Stiff: The Curious Lives of Cadavers. It was so disturbing that I didn’t get beyond learning that cadavers are used for all sorts of science, including cosmetic surgery and crash testing cars. To me, donating my body to science is a way to advance medical knowledge. Having someone practice a nose job or tummy tuck on my dead body is less idealistic. I know those procedures are not always for cosmetic reasons, but the vast majority are.

I remain undecided about donating my entire body to research. Fortunately, this is not a decision I have to make. Not only because I don’t plan to die soon, but because the migraine registry will allow me to donate brain tissue to migraine research without committing the rest of my body to science.

Updates to Post on Migraine Drugs & Cognitive Dysfunction, Dementia

I accidentally published an old draft of the post on migraine drugs and cognitive dysfunction and dementia is older adults. Here’s the substantially updated version.

Some Migraine Drugs Linked to Cognitive Impairment, Dementia in Older Adults

migraine drugs linked to dementia, cognitive impairment in older adultsThis post was updated at 12:40 p.m. PDT on April 19, 2016.

What kind of long-term impact will taking migraine drugs have on my body? Am I trading a better present for more problems in the future?

These and similar questions have flitted through my mind for years. I usually push them aside—I need these drugs to function, so I don’t feel like I have much choice. Besides, an abstract future worry is so vague that it doesn’t seem to require much attention. Thanks to new research, that worry no longer seems abstract or vague.

Cognitive impairment and dementia in older adults have been linked to anticholinergic drugs, which block the neurotransmitter acetylcholine, in an increasing number of studies over the last decade. Some popular antihistamines, antidepressants, and anti-nausea meds used as migraine drugs have anticholinergic effects.

The research may not be cause for alarm, which I’ll explain in a moment. The first question you want answered is likely: Which drugs put me at risk?

Migraine Drugs With Anticholinergic Effects

This list contains drugs I’m aware of people using for migraine, but it is not an exhaustive list of anticholinergics. Indiana University has a more complete list of anticholinergic drugs (PDF). A JAMA article on the topic also includes Vivactil (protriptyline) and Compazine (prochlorperazine). ACB score refers to “anticholinergic cognitive burden,” which determines if a drug has mild or moderate anticholinergic effects.

Mild Anticholinergic Effect (ACB Score 1)

  • Actiq (fentanyl)
  • Duragesic (fentanyl)
  • Effexor (venlafaxine)
  • Flexeril (vyclobenzaprine)
  • Immodium (loperamide)
  • Valium (diazepam)
  • Wellbutrin (bupropion)
  • Xanax (alprazolam)

Moderate Anticholinergic Effect (ACB Scores 2 & 3)

  • Advil PM (diphenhydramine)
  • Atarax (hydroxyzine)
  • Benadryl (diphenhydramine)
  • Dramamine (dimenhydrinate)
  • Elavil (amitriptyline)
  • Flexeril (cyclobenzaprine)
  • Gravol (dimenhydrinate)
  • Norflex (orphenadrine)
  • Norpramin (desipramine)
  • Pamelor (nortriptyline)
  • Periactin (cyproheptadine)
  • Phenergan (promethazine)
  • Sinequan (doxepin)
  • Tegretol (carbamazepine)
  • Tylenol PM (diphenhydramine)
  • Vistaril (hydroxyzine)

Anticholinergic Burden Unknown

(have an anticholinergic effect, but do not have an ACB score)

  • Compazine (prochlorperazine)
  • Vivactil (protriptyline)

Anticholinergic Drugs, Cognitive Impairment, and Dementia: The Research

Keep in mind that:

  1. These studies do not provethat anticholinergic drugs cause cognitive impairment or dementia. They have found that a link exists between taking the drugs and cognitive impairment or dementia.
  2. All published studies have focused on older adults, most with an average participant age in the early 70s. It is speculated that increased age makes the body more susceptible to these effects, possibly because these drugs permeate the blood-brain barrier more readily in older people.

Risk depends on strength of cholinergic effect

Drugs with a mild cholinergic effect (an ACB of 1) can cause cognitive impairment in older adults within 90 days of continuous use. Those with a strong cholinergic effect (ACB of 2 or 3) can cause cognitive impairment in 60 days of continuous use. Non-continuous use can also have an impact, though the exact length of time varies. Cognitive effects were increased with the number of anticholinergic drugs a patient took. (See Just 2 Months’ Exposure to Anticholinergics Affects Cognition)

Dose matters (somewhat)

The higher the drug’s dose, the greater the risk, according to a study published in 2015. However, even at the minimum effective dose, taking the drugs for prolonged periods were linked to a greater likelihood of cognitive impairment or dementia than for those not taking anticholinergic drugs. “This is not excessive use,” said the lead author Shelly Gray, PharmD, from the University of Washington. “Many of these agents are used chronically, and chronic use—even at low doses—would put you in the highest risk category.” (See ‘Strongest Evidence Yet’ Links Anticholinergic Drugs, Dementia)

Changes in the brain

Brain imaging found lower brain metabolism and reduced brain sizes among participants taking anticholinergics, as reported in a study published this week. Participants taking the drugs also scored lower on cognitive tests than those not taking the drugs. This is the first study looking at the underlying biology of the link identified by earlier research. (See IU Scientists: Brain Scans Link Physical Changes to Cognitive Risks of Widely Used Class of Drugs)

Age of participants

The published studies I found are focused on older adults. Researchers believe that a person’s central nervous system becomes more sensitive to anticholinergic medications with age. It could be that younger patients don’t have the same risks, but that’s uncertain. This warning from Dr. Gray haunts me: ‘There is no data on how these drugs may affect younger people, but I personally will avoid taking anticholinergic agents.”

I found one study presented at a conference that looked at the ACB of younger patients with chronic pain. Participants with chronic pain had significantly higher ACB scores than healthy participants and their cognitive function appeared to be affected. The burden was greatest in patients aged 30 to 39. (See Pain Patients at Cognitive Risk From Anticholinergic Burden?)

Cognitive Impairment vs. Dementia

Cognitive impairment and dementia are very different things. Several studies show that cognitive impairment due to the drugs could be reversible. The drugs could magnify symptoms of an already present mild dementia or bring symptoms on earlier than would have happened otherwise. However, brain atrophy, as found in the study published this week, doesn’t sound reversible.

What’s the Actual Risk?

No one knows for sure. The research is concerning, but is far from conclusive. Many questions still remain. Talk to your doctors and pharmacists for advice that’s best suited to you—it will depend on your age, the medications you take and why you take them, how effective the medications are for you, what alternative medications might help you, and other health problems you may have. Please don’t stop taking your medications without first talking to your health care providers—doing so could put you at risk of other problems.

I plan to ask all my doctors and pharmacists for input. My gynecologist and endocrinologist haven’t prescribed anticholinergics, but I trust them both and want them to weigh in on this, too.

Why I’m Sharing This Research

I freaked out when I first learned about this research last year. I started to write about it, then set it aside. I decided the research was too inconclusive to scare people by reporting it. When I saw the study published this week, I changed my mind. The research is still very preliminary and I don’t want people to panic. Nonetheless, patients should be aware that this research exists so they can make an informed decision about which medications are best for them. Your doctor will probably tell you that it’s not cause for concern, but it’s better to be able to ask them about it than remain completely in the dark.

Kerrie’s Uneasy Truce

The two medications I take daily, cyproheptadine and Wellbutrin, are on the list. My paternal grandmother had Alzheimer’s and I have been afraid of the disease for as long as I can remember. I doubt I would have started the drugs if I’d known about this research. I’m not sure that’s a good thing. These medications allow me to get out of bed. The past four years have been relatively manageable thanks to them. They have improved my quality of life enough that I’ve been able to aggressively pursue other treatments.

I was terrified when I started writing this post, but I have calmed down considerably the more I have learned. This is preliminary research. Cause and effect hasn’t been established. I’m 28 years younger than the average patient in the studies. I’m actively trying to find alternative treatments to these medications. Migraine research is making tremendous strides in preventive treatment. Of course I’m still a little worried that I’m trading the present for the future. I’d be worried about that even without these drugs.

Correction: $10 Million to UCLA, $8 million for Migraine Research

The Goldbergs gifted $10 million to UCLA Health Sciences: $8 million will go to migraine research through the UCLA Goldberg Migraine Program, $1.5 million will be for the Goldberg Health System Fund, and $500,000 will establish the Goldberg Head and Neck Fund in the department of head and neck surgery.

From the press release:

UCLA Health Sciences has received a $10 million gift, most of which will support multidisciplinary research on migraine, a debilitating neurological disorder that affects 36 million people in the U.S.

In addition to the portion of the gift supporting migraine research, $500,000 will establish the Goldberg Head and Neck Fund in the department of head and neck surgery under the direction of Dr. Gerald Berke. The remaining $1.5 million will establish the Goldberg Health System Fund.

I’m sorry for the mistake. This is embarrassing, but I even double-checked the numbers and understood the $2 million to be in addition to the $10 million for migraine research. Perhaps the tears of joy for clouded my vision (and my ability to add).

Whether the amount for migraine research is $10 million or $8 million, it doesn’t diminish the real value of the gift: hope. That’s reflected in almost every thank you I read. As is the idea that this gift shows us that our lives matter. Writing those words makes me sad, but I’m not surprised it was a common theme. (That last sentence quickly evolved into a discussion of NIH funding for migraine relative to other diseases. It’s an important discussion to have, but not appropriate in the post. I’ll share it soon.)

Thanks to reader Julianne for pointing out the mistake.

$8 Million Migraine Research Gift: A Thank You to Wendy & Leonard Goldberg

Dear Mr. and Mrs. Goldberg,

As I learned of your generous migraine_hopegift to UCLA for migraine research, I was so overjoyed and overwhelmed that I couldn’t stop crying. The news is exciting for me personally, but the tears were not only for me. They were for all the amazing people who have endured enormous pain and sorrow because of this disease. In UCLA’s press release, Dr. Charles said, “Migraine is generally under-recognized as a major medical problem, in part because it is not fatal. But it is not hyperbole to say that it can ruin lives.” He is so right.

In December 2009, years of constant, ever-worsening pain, nausea, fatigue, and cognitive dysfunction nearly devoured my last glimmers of hope. I went to bed each night wondering if I would survive the next day. I later learned that my husband had the nearest in-patient psychiatric clinic programmed into his phone and came home for lunch to make sure I hadn’t attempted to take my life. His unwavering support, a team of great doctors, and amazing family and friends got me through those bleak, hopeless days.

I am extremely fortunate. So many people I hear from as a patient advocate are lacking social support, financial resources, and access to health care providers who understand migraine. The stories are heartbreaking—lost marriages, estranged children, opiate addiction, poverty, homelessness, suicide. Living with any chronic illness is difficult. When the disease is poorly understood and heavily stigmatized, as migraine is, it can render a person’s life, and even self, unrecognizable.

Upon hearing of your donation, I shed tears of joy for my own future, of course, but mostly I cried for the millions of people whose lives are in turmoil because of migraine. Your donation will fund research that could ultimately give millions of people relief and reduce the stigma of migraine. The magnitude of your generosity cannot be overstated, but you’ve also done something that, to me, is even more remarkable. You have given hope to people who struggle desperately to see beyond a life dominated by disabling migraine attacks. You have given us the invaluable gift of a glimpse of a better future.

Thank you. Thank you so very much.

Sincerely,
Kerrie Smyres
