In India, more than 4 million people have some form of dementia. Dementia is usually a disease of the old age. It is characterized by progressive loss of memory, language, judgement and planning impairment of daily activities, and reduced social interaction.
The number of elderly population in India is growing rapidly. India’s elderly population is estimated at 10 crore in 2011, and is projected to reach 20 crore by 2030. United Nations Population division statistics suggest that the share of India’s population ages 60 and older is projected to climb from 8 percent in 2010 to 19 percent in 2050.
Is it possible to delay dementia onset?
Researcher followed 960 participants over 4.7 years in the Memory and Aging Project. Participants were between 58–99 years and had completed a food frequency questionnaire and 2 or more cognitive assessments.
Study concluded consumption of green leafy vegetables at least once in a day along with certain nutrients such as phylloquinone, lutein, nitrate, folate, alfa-tocopherol may help to slow cognitive decline by at least 11 years with aging.
With ageing, individual experiences decline in the cognitive ability. Ageing person experiences reduction in following activities:
1) Processing speed
Processing speed is a speed with which cognitive activities are performed as well as the speed of motor responses.
Attention is a ability to concentrate and focus on specific stimuli.
Changes in memory with age may be related to slow processing speed, reduced ability to ignore irrelevant information, and decreased use of strategies to improve learning and memory.
Verbal fluency i.e. ability to perform a word search and generate words in a certain amount of time.
5) Executive Functioning
Executive functions includes a wide range of cognitive abilities such as the ability to self-monitor, plan, organize, reason, be mentally flexible, and problem-solving.
