Preventive neurologist Dr Richard Isaacson stared on the numbers on the fax in astonishment. Blood biomarkers of telltale indicators of early Alzheimer’s illness within the mind of his affected person, 55-year-old entrepreneur Simon Nicholls, had all however disappeared in a mere 14 months.
“I needed to catch my breath. It was an entire shock: The blood checks on his mind had normalized,” mentioned Isaacson, director of analysis on the Institute for Neurodegenerative Ailments in Boca Raton, Florida.
Was this beautiful end result the work of some new miracle drug designed to fight dementia? By no means. It is a story of old style grit and willpower.
“Simon was on a mission, as if the Grim Reaper was peering over his shoulder. He was going to kick ass and take names,” Isaacson mentioned.
Nicholls decreased his danger of creating Alzheimer’s by way of way of life modifications beneficial by Isaacson, together with weight loss plan, train, decreasing stress and optimizing sleep, together with a number of strategically chosen dietary supplements and drugs prescribed by his heart specialist.
“I used to be very nervous,” Nicholls advised CNN Chief Medical Correspondent Dr. Sanjay Gupta in his new documentary, “The Final Alzheimer’s Affected person,” which is airing on “The Complete Story with Anderson Cooper.”
“I’ve a 3-year-old son and an 8-year-old son. It’s actually essential for me, as I grow old, to attempt to be there for them sooner or later,” he mentioned. “There are various [changes] in way of life you are able to do to hopefully push the illness backwards and provides your self extra time, which is all we want till we discover a remedy.”
When it got here to genetics and dementia, Nicholls had drawn the quick straw. He carried two copies of the APOE4 gene, one from every dad or mum, which can enhance the danger of creating Alzheimer’s not less than tenfold.
“Sadly, my mum handed away from what we predict is Alzheimer’s in her 70s,” Nicholls mentioned. “For the final 10 years of her life, she simply sat in a chair, rocking, whereas on about 14 drugs. I’d a lot slightly have an extended well being span after which simply go rapidly.”
Not everybody with one and even two copies of APOE4 develops Alzheimer’s, nevertheless, making a tantalizing alternative. Can an individual diminish their genetic danger for Alzheimer’s by way of way of life and numerous medical interventions, particularly if began early, earlier than an excessive amount of harm is completed?
Isaacson, who additionally has a household historical past of Alzheimer’s, believes the reply is sure. He started the first US clinic devoted to Alzheimer’s prevention in New York Metropolis in 2013 earlier than shifting his program to Florida in 2021. His research has proven that following a dozen or extra way of life interventions, when practiced 60% or extra of the time, can enhance cognitive perform, especially in women.
Right now, scientists all over the world are additionally investigating the influence on cognition of such lifestyle changes as a healthy plant-based diet, stress reduction, strength training, aerobic exercise and quality sleep habits — behaviors that Isaacson and his workforce outlined in a latest overview published in Nature.
“I don’t use the time period ‘reverse.’ I don’t know what reverse means in the case of the sector of Alzheimer’s,” Isaacson mentioned. “However the outcomes we’ve seen with Simon and another sufferers in our analysis are extraordinarily thrilling.”
How the center and the mind are intertwined
Alzheimer’s isn’t the one pathway to a lifetime of dwindling reminiscence and the shortcoming to assume, plan and work together with family members.
Vascular dementia, the second most typical kind of dementia after Alzheimer’s illness, may be brought on by atherosclerosis, a buildup of plaque within the arteries that may result in coronary heart assaults, stroke, blood clots and extra, all of which may additional harm the physique and mind.
Poor hearts and their penalties can run rampant in a household over generations, a reality Nicholls knew all too nicely.
“My entire household had limitless coronary heart assaults, leading to my grandfather on my mom’s facet dying round age 50,” he mentioned. “My mom had three coronary heart assaults, the primary at age 50, then a triple bypass earlier than she went on to develop dementia.”
Carrying an APOE4 gene additional will increase the risk for heart disease in addition to dementia, consultants say.
“My sister had three coronary heart assaults, and after I was 40, I used to be advised that I had atherosclerosis, with a ridiculously large coronary artery calcium rating of like 1,500 and occlusions in about 96% of my arteries.” A traditional coronary artery calcium rating is zero.
For a person within the prime of his life, the information was crushing. Docs tried to make use of way of life modifications and statins to reverse the plaque buildup however lastly resorted to surgical procedure, opening three of Nicholls’ arteries with stents. He additionally started utilizing an injectable drug referred to as evolocumab, designed to spice up the liver’s means to take away “dangerous” low-density lipoprotein, or LDL, from the physique.
Slowly, Nicholls’ coronary heart situation started to enhance, however the dangerous information didn’t finish there. A mind scan discovered telltale indicators of vascular harm in Nicholls’ mind, which happens when the tiniest blood vessels are starved of oxygen.
“The medical doctors mentioned I had too many white matter lesions. I advised myself that since I now had my coronary heart roughly beneath management, it was time to show to my mind,” Nicholls mentioned.
In January 2023, Nicholls turned participant No. 34 in a novel scientific trial at Isaacson’s Florida middle. The trial is designed to uncover cognitive danger components and counter them with a personalised plan of assault. (Full disclosure: I’m participant No. 20 in the identical trial; you possibly can read about my experience here.)
“The general aim of the examine is democratize entry to preventive neurology care by finally utilizing at-home blood testing to cost-effectively attain the most individuals,” Isaacson mentioned.
As a part of the trial, Nicholls underwent a battery of checks, together with a singular blood take a look at that may observe levels of amyloid, tau and different hallmark biomarkers for Alzheimer’s illness and different degenerative situations. Deposits of amyloid can start accumulating within the mind a long time earlier than signs start, even in a person’s 30s and 40s.
“Simon’s first take a look at got here again with a rating of 70. Something over 58 was optimistic for amyloid within the mind,” Isaacson mentioned. “The outcomes backed up the amyloid PET scan Simon had taken in 2019, the place I might see the plaque in his mind.”
Nicholls wanted to free weight, so he started taking tirzepatide (the lively ingredient within the drugs Mounjaro and Zepbound), one of many newer injectable medication that suppress urge for food by stimulating hormones that management blood sugar ranges.
On the identical time, Nicholls was inspired to step up his bodily exercise by incorporating power coaching 3 times per week whereas including 45 to 60 minutes a day of zone 2 train, through which you briskly walk, ruck, jog or cycle at 60% to 70% of your coronary heart price.
“I like going for a stroll each morning at dawn for an hour and a half with a podcast. I get in 10,000 steps or extra daily. I’m very constant,” Nicholls mentioned. “I additionally do a really gradual full-body exercise with weights 3 times per week for an hour’s time.”
Avoiding sugar, synthetic sweeteners, alcohol and ultraprocessed meals is a should, as is following a plant-based meal plan such because the Mediterranean diet.
“Once I first noticed Simon, he had a little bit of a center, like most guys of their 50s,” Isaacson mentioned. “Once I noticed him at 9 weeks, I did a double take. He was completely buff, ripped even.
“Inside these 9 weeks, he had misplaced 21 kilos, about 80% of that fats, and placed on muscle, which was glorious,” Isaacson added. “I virtually didn’t acknowledge him.”
The burden loss and elevated muscle mass lowered Nicholls’ fasting blood sugar ranges, ending his march towards diabetes, whereas some tweaks to his ldl cholesterol drugs additional optimized his good and dangerous ldl cholesterol numbers.
In August 2023, it was time to repeat the blood take a look at for amyloid. By then, the corporate that administers the checks had added a measurement for tau, one other key hallmark signal of Alzheimer’s, frontal lobe dementia and Lewy physique illness.
“Simon’s amyloid chance rating on the brand new APS2 take a look at had dropped to 53, which was phenomenal,” Isaacson mentioned. “However he was nonetheless optimistic, as something between 48 and 100 is taken into account to mirror a excessive chance of amyloid mind plaques on a mind scan.”
Now that the massive issues of ldl cholesterol, insulin, weight loss plan, train and fats mass have been addressed, it was time “to activate the screws,” Isaacson mentioned, with personalised suggestions based mostly on Nicholls’ biology.
“We optimized Simon’s omega-3 fatty acid ranges, which is very essential for folks with APOE ε4, as they want extra omega-3. We additionally added B complicated nutritional vitamins to regulate elevated homocysteine in his blood,” Isaacson mentioned. “Nonetheless, we might not give B complicated nutritional vitamins to anybody who didn’t have increased homocysteine ranges.”
Elevated homocysteine, which is an amino acid utilized by the physique to make protein, is a risk factor for mind atrophy, cognitive impairment and dementia. A September 2010 randomized controlled trial discovered that supplementation slowed mind atrophy in folks with gentle cognitive impairment.
Within the meantime, Nicholls, an avid researcher who likes to learn medical journals, was including some interventions of his personal.
“I’ve steam and sauna rooms in my residence, I do a number of that. I find it irresistible,” he mentioned. “I’ve tried chilly water plunges, and I’ve lists of issues to do I get from podcasts, from strolling to sleeping to gratitude to yoga to sleep routines.
“However there’s one factor I do this Dr. Isaacson doesn’t agree with: I get stem cell injections twice a yr,” Nicholls added. “Sadly, I’ve arthritis in my arms, and that positively feels higher after I use stem cells, and I wish to assume they might be serving to my mind, as nicely.”
There was another massive situation to deal with: Nicholls’ sleep, or lack of it, which studies have proven can hasten cognitive decline and Alzheimer’s.
With enterprise all over the world, Nicholls is a frequent flyer with “horrible sleep” attributable to jet lag and insomnia. “I’m additionally a worrier kind of particular person,” he confessed.
Including a sleep treatment permitted for insomnia helped, “however Simon actually must deal with his sleep by enhancing his sleep hygiene with a extra common sleep schedule,” Isaacson mentioned.
On Halloween 2023, the subsequent APS2 rating arrived. Amazingly, Nicholls had decreased the quantity of amyloid and tau in his blood to 40: He was testing detrimental in blood for indicators of Alzheimer’s.
Shocked and amazed, Isaacson remained skeptical. “I used to be very cautious. You recognize, promise to not overpromise. I wanted to retest.”
A number of days earlier than Christmas, the repeat take a look at outcomes arrived. When it too was a detrimental discovering of 40, Isaacson determined to inform Nicholls in particular person.
“Dr. Isaacson drove all the way in which from Boca Raton to Miami excited, very blissful,” Nicholls mentioned. “We walked on a seaside collectively, and we have been ecstatic that we’d really been ready go from optimistic to detrimental for amyloid.”
Though Nicholls is ecstatic in regards to the enhancements, he’s additionally very humble about his efforts to enhance his well being.
“I’m actually not all that compliant. To conform is simply horrendously tough, proper? After all I need to have a beer or a hamburger or one thing silly. I like gummy bears and consuming crappy meals,” he mentioned.
“It’s helped that I’ve some nice medical doctors to assist me, however to be sincere, my largest motivator are my kids,” Nicholls added. “I’d like to see my sons get married and have their very own youngsters, and to try this, I’ve to place within the work to remain the way in which I’m now.”
Even decrease amyloid ranges and a bigger hippocampus
It seems Nicholls is nicely on his means towards that aim. In March, his APS2 rating had dropped to 25, an unbelievably low quantity.
Not solely was Nicholls blood detrimental for amyloid and tau, the take a look at instructed that his mind amyloid is likely to be regular, with no distinguishable indicators of the illness. The one technique to definitively show this, nevertheless, could be to repeat his amyloid PET scan, Isaacson mentioned.
“What actually drove his rating down was the amyloid worth,” Isaacson mentioned. “It normalized at .101, which is like loopy good. That’s not matter for dialogue; for amyloid, .1 or above is regular.”
Much more startling: Mind quantity scans confirmed that the hippocampus, the tiny seahorse-shaped organ accountable for reminiscence, had really grown in quantity in Nicholls’ mind since he began the intervention.
In early Alzheimer’s phases, the hippocampus loses tissue rapidly after which atrophies because the illness progresses.
Regardless of these superb outcomes, Isaacson stays cautious. In spite of everything, that is one particular person, and comparable findings haven’t been been replicated in a bigger, extra managed pattern and revealed in a peer-reviewed journal.
“I don’t consider within the time period ‘reverse’ as a result of I don’t know what’s going to occur if the particular person stops doing the intervention,” Isaacson mentioned. “I additionally don’t know if the mind may normalize for a brief time period after which, 5 years later, catch up. Till I’ve extra information, I don’t assume that reverse is the fitting phrase.”
That doesn’t cease his surprise on the outcomes and his gratitude to Nicholls for his persevering with dedication to the examine and the personalised interventions.
“I nonetheless can’t consider it. I’d seen this earlier than, however solely in people who find themselves taking anti-amyloid drugs,” Isaacson mentioned. “Once you work your complete profession and are advised by everybody, ‘It’s not attainable to do that,’ and then you definately see it — nicely, I’m nonetheless humbled and amazed.”
