Alzheimer’s disease is a neurodegenerative disorder that occurs due to the age-related decline in the cognitive functions of the brain. Inflammation, oxidative stress due to free radicals, and toxic damage can accelerate this process.

The common signs of this condition include reduced memory, attention span, and focus. It may also affect the problem-solving and rational thinking skills of the patient.

What does research say?

Research studies have shown that height could be one factor that can determine the patient’s risk of developing Alzheimer’s disease. This study has shown that men with Alzheimer’s are more likely to be shorter compared to those without this condition.

However, there was a very small difference in the height of women with or without Alzheimer’s disease. This showed that the impact of height on the risk of this condition is higher in men than in women.

Men with a height of more than >179.7 cm or 70.75 inches had a 59% lower chance of developing Alzheimer’s disease compared to those with a height less than 169.5 cm or 66.75 inches. [1]

Taller women were also found to have a comparatively lower risk of AD to some extent.

Adult height and cognitive performance

Another observational study has evaluated the impact of height on the risk of Alzheimer’s disease at a much deeper level. It has linked the increased adult height with the improved cognitive performance of the person.

This means men and women who are taller tend to have better cognitive skills including memory, attention span, focus, and rational thinking skills.

This indicates that they might be more resistant to the impact of the age-related decline in the cognitive functions that occurs due to Alzheimer’s disease.

Hence, patients who are taller could have a lower risk of developing Alzheimer’s disease as their cognitive skills are well developed compared to those of people with a shorter height.

The findings of this study have suggested that the biological processes that influence height might have a role to play in the etiology of Alzheimer’s disease. These biological processes might trigger or slow down the cognitive decline and thus, modify the risk of Alzheimer’s disease. [2]
