Description
Preventing dementia may be cheaper at the level of whole populations than person by person. Naaheed Mukadam and six co-authors model what would happen in England if governments acted on known risk factors. The list runs from smoking and excess alcohol to the diet drivers of hypertension and obesity, air pollution, and head injury. Their Markov model follows lifetime dementia risk with and without each policy.
Every intervention paid for itself. Minimum alcohol pricing was projected to save 280 million pounds and gain about 4,800 healthy life years. Reformulating food to cut salt and sugar saved billions and gained tens of thousands of healthy years. Low-emission zones, a ten percent cigarette price rise, and compulsory bicycle helmets for children also saved money while gaining health. The authors advocate the full package as cost-saving prevention.
