What causes cognitive decline?

Does high blood pressure lead to holes in our brain?

Does low blood pressure lead to holes in our brain?

Does diabetes lead to holes in our brain?

Does sleep apnea lead to holes in our brain?

Does atherosclerosis lead to holes in our brain?

How about heavy metals, nutritional deficiencies (B12, sunshine) and sedentary lifestyle?

For Dr Greger's videos on the subject, please see Alzheimer's and WFPB. In particular, see Alzheimer's May Be A Vascular Disease.

[Great Video!] Is diabetes & hypertension related to dementia? An insightful presentation by Dr Peter Rogers.

Key idea: capillary wall thickening ("capillary basement membrane" in particular; such thickening is a common feature of diabetes and hypertension due to scarring and inflammation of capillaries) → reduced oxygen supply to cellular structures (neurons, for example) → neuron death → cognitive impairment (dementia).

[The situation is exacerbated by factors like rouleaux formation of RBCs ('blood sludge effect' due to high fat meals), vasoconstriction due to excess sodium (and low potassium, low magnesium), and ramping up of neuronal metabolic demand due to excitotoxins (found in processed foods with MSG, MfG and so on). All of these concepts are explained in detail in other videos by Dr Peter Rogers.]

What to do? Take diabetes and hypertension very seriously (before we become cognitively so impaired that it's too late to take any action): adopt Low Fat, Low Sodium WFPB guidelines diligently. Avoid processed foods.
