Lower Risk of Dementia when Older Adult Retains Sensory Capabilities
Alzheimer’s and Dementia: The Journal of the Alzheimer’s Association.“Sensory impairments could be due to underlying neurodegeneration or the same disease processes as those affecting cognition, such as stroke,” said first author Willa Brenowitz, PhD, of the UCSF Department of Psychiatry and Behavioral Sciences.“Alternatively, sensory impairments, particularly hearing and vision, may accelerate cognitive decline, either directly impacting cognition or indirectly by increasing social isolation, poor mobility and adverse mental health.”While multiple impairments were key to the researchers work, the authors acknowledged that a keen sense of smell, or olfaction, has a stronger association against dementia than touch, hearing or vision.
