Final answer:
The question regarding the percentage of New Hampshire residents diagnosed with Alzheimer's disease or related dementia cannot be precisely answered without specific local data. Approximately one in every eight individuals over 65 years is affected by Alzheimer's, and both genetic and environmental factors play a role in the disease's prevalence.
Step-by-step explanation:
The question pertains to the percentage of people in New Hampshire (NH) who have been diagnosed with Alzheimer's disease or related dementia. Based on statistics, approximately one in every eight people age 65 or older has Alzheimer's disease. Given that the disease is the most common cause of dementia in the elderly and that there are genetic factors at play, estimating the exact percentage for NH residents would require specific regional data, which has not been provided here. It is also important to note that Alzheimer's disease can have both early onset and late-onset forms, with genetic mutations contributing to early onset Alzheimer's, affecting under 5% of patients.
Looking at the percentages of population diagnosed presented, NH's percentage would fall within one of those ranges, but without local data, an exact figure cannot be determined. Population studies and the aging demographic indicate a rise in Alzheimer's patients by 2050. Moreover, disparities in percentages can arise from methodological differences in research studies, sample sizes, and local environmental and genetic factors influencing Alzheimer's prevalence.
