Strategies for Alzheimer’s Prevention: What We Have Been Doing All Along
The Bale Doneen Method emphasizes the treatment and prevention of inflammation and oxidative stress as a means for controlling cardiovascular disease and risk. Recent studies that focused on the many aspects of health affecting Alzheimer’s risk unsurprisingly report significant overlap with the medications and supplements we routinely recommend in our practice. Because Alzheimer’s Disease, at its core, is a multifactorial disease, its treatment requires our multifactorial and personalized approach.
Vitamin B12
Vitamin B12 deficiency has been linked to an in creased risk of dementia or worsened cognitive perfor mance. This is logical, as there are multiple biochemical pathways involved in Alzheimer’s Disease affected by B12 deficiency. Studies showed that patients suffering from Alzheimer’s had lower plasma B12 levels than healthy controls, and supplementation of B vitamins was reported to improve cognitive function.

CoQ10 (Ubiquinol)
CoQ10 (Ubiquinol) is implicated in numerous neurodegenerative diseases, including Alzheimer’s Disease. In a recent study of CoQ10, supplementation protected the brain from inflammation and reduced beta-amyloid (the plaque found in the brains of Alzheimer’s patients) production while suppressing oxidative stress. CoQ10 is also known to protect the brain by decreasing brain atrophy (shrinkage).

Statin Therapy (Crestor, Pravastatin, Simvastatin, etc.)
Statin medications, used frequently for their anti-inflammatory and oxidative stress lowering effects, have also been found to significantly impact the progression of mild to moderate Alzheimer’s Disease. In short, statins protect the brain. Statins play a neuroprotective role by lowering the dangerous cholesterol levels, while also reducing amyloid beta peptides and tau proteins (p-tau) in the brain (inflammatory proteins found in the brain of Alzheimer’s patients).

Pioglitazone (Actos)
Pioglitazone, used primarily in the treatment of Type 2 Diabetes and insulin resistance, has recently garnered attention for its role in Alzheimer’s Disease prevention. Insulin Resistance is so heavily implicated in the pathogenesis of Alzheimer’s that it is often referred to as “Type 3 Diabetes” or “Diabetes of the brain.” Pioglitazone is a powerhouse when it comes to Alzheimer’s Disease prevention, due to its ability to increase insulin sensitivity of the brain and impr ove glucose (sugar) utilization, reduce inflammation and reduce brain atrophy (shrinkage). Pioglitazone has been shown to improve learning and memory, and studies suggest that su perior effects are seen when treatment is started prior to the onset of symptoms.

ACE inhibitors and Angiotensin Receptor Blockers (RAS)
ACE inhibitors (i.e.: Ramipril) and ARBs (i.e.: Losartan), used frequently for blood pressure control and arterial wall protection, may also affect Alzheimer’s risk and symptomatology. As the Renin Angiotensin System (RAS) is involved in regulating activities such as lear ning, memory, cognition and emotional stress, brain RAS has been shown to be associated with Alzheimer’s Disease. Inhibiting the RAS system with this class of medication presents another opportunity for overlapping cardiovascular and neuroprotective therapy.

Vitamin B3 (Niacin)
A power player in multiple areas of cardiovascular care, vitamin B3 also holds promise in the neurological world. Niacin protects the brain through lipid pathways and by inducing the breakdown of problematic amyloid-beta plaques. In fact, supplementation aside, research has established that increased dietary intake of niacin is associated with impr oved cognition and reduced risk of AD later in life.

Conclusion
While we have always believed wholeheartedly in our mantra “Healthy Heart, Healthy Brain,” Alzheimer’s Disease researchers are now coming to the same conclusions. When we protect arterial health in the heart and elsewhere, we are also keeping the brain healthy and sharp for life.
