For some time now its been known that sensory input is important in helping to prevent or reduce the symptoms of dementia.
Factors improving eyesight such as properly prescribed specs and surgery to correct cataracts are useful.
Evidence recently published also confirms the help that can be gained from hearing aids. Good hearing levels are helpful for social interaction which is so important in the management of dementia.
The NHS provides good quality hearing aids but the private sector too gives an excellent alternative, often with more cosmetically appealing aids.
See your GP for an NHS referral or visit one of the other high street providers such as Specsavers for an NHS aid. Self referral to a high street audiologist is OK for a private aid.
