She was diagnosed as Lewy Bodies Dementia.
Lewy Bodies Dementia (LBD)
The development of Lewy Bodies in the neurons of the cerebral cortex or the brain stem impairs the function showing (1) cognitive dysfunction such as a loss of memory or inability to recognize the situation, (2) visual or auditory hallucination, (3) mobility impairment leading to inability to walk due to stiff muscles. The cause of LBD is not understood. There is no cure of LBD and the treatment is symptomatic such as loosening the muscles with medications.
But she recovered from the dementia in a certain way.
What leaded to dramatic recovery was ballroom dance.
Her son had had her try various things seemed effective in dementia, but nothing had been effective. One day when she heard Tango in his car, her fingers started to move with the rhythm. When she was young, she was enjoying ballroom dance with her boyfriend. Her son took her to ballroom dance classes to have her watch their dance. 2 weeks later she told her son that she wanted to dye her hair. One month later she chose and wore a brightly colored shirt and danced with the instructor, and her smile came back.
Why ballroom dance helped her recovery from dementia?
A lot of researches that ballroom dance is effective in maintaining and improving a cognitive function have been reported recently. The movement of ballroom dance is not only an aerobic exercise but also an intellectual activity which makes you memorize complicating steps and dance not to make a mistake thinking about the steps. Doing an exercise and intellectual activity simultaneously is effective in improving a cognitive function.
Another important point leading to her dramatic improvement is that ballroom dance was her sweet memory. So she could continue the dance whilst enjoying it, resulting in the dramatic recovery.
One year after starting ballroom dance, she went to Hawaii with her family.
According to a research in USA, Recreational Activities that lower the risk of dementia are:
(1) Ballroom dance: Decreased by 76 %
(2) Board games: Decreased by 74 %
(3) Playing musical installments: Decreased by 69 %
The similarity among these three activities is that they involve communication with other people.
