Sexual behaviour can cause problems. There is no reason why a couple cannot continue any sexual relations that were occurring prior to the development of the condition as long as both parties are happy. As the sufferer becomes more disabled, sexual activity usually declines naturally and both can accept this (this occurs in many other conditions, though in some diseases it may only need to be a temporary cessation).
Difficulty may arise when the sufferer (usually a man) has a resurgence of sexual urges or a wish to continue previous relations but the wife is now unhappy about this and does not want it to happen. Usually the sufferer can be persuaded to stop the advances and often the urges wear off. However, it can be very tiring and embarrassing if it becomes a persistent problem.
In a few cases of advanced dementia both men and women may fondle, touch or actively rub their genitals/private parts. This can progress to full masturbation. As with the unwanted sexual advances towards a partner, this activity can be very distressing for carers and embarrassing for all observers. Keeping a person occupied and hence distracted may help (as well as checking that there is no local cause of irritation). Appropriate clothing can lessen the activity (trousers for women, trousers with no fly opening for men). If however the sexual activity is at a level unacceptable to the carer and the dignity of the sufferer is at stake then special help should be obtained, e.g. psychogeriatrician/ mental health for the elderly as specific medication can be tried.

Have practical considerations in mind when you pick out your sunglasses. Read the label when examining the light transmission factor. Eyeglasses for the sun should transmit no more than 30 percent of the light; select those that transmit only 10 to 15 percent for use on the beach, water, or snow. Make sure they’re dark enough so that you can’t see your eyes through them when looking in a mirror. Polarizing lenses do help reduce glare during boating or driving, but for intense glare, mirrored lenses are best.
Gradient density lenses are made darker at the top of the glass. Phototropic lenses adjust to the light intensity and serve well under a wider variety of light conditions. Choose phototropics that remain rather dark in their faded state. Gray or smoke-colored lenses are least likely to distort color. Green and brown are better, but stay away from the high-fashion colors such as pink, orange, yellow and blue, which alter color perception too much by letting through an overabundance of light.
Avoid wearing sunglasses indoors or after dark; it’s a bad habit which may lead to night vision impairment. In a tanning hut or under an ultraviolet lamp, substitute sun goggles for sunglasses so as to not bring on damage to the sensitive areas of the eyes. You can burn them.
Burned eyes, indeed, are the most common summer eye problem, reported Robert J. Crossen, M.D. a former trustee   of   the American   Association   of Ophthalmology.
Ultraviolet rays will damage the cornea, too, a problem that may not reveal itself until the next day. Then you may awaken from sleep with searing pain and a feeling of sand grains in the eyes. Sometimes the cornea could be so scarred, vision is impaired.
Night vision may be reduced by too much exposure to the sun. You might not be able to drive home safely after staying in the bright sun for a prolonged period. Those who have their occupations on the sea, in the snow, or on desert sands, could develop cataracts from an excess exposure to sunlight accumulated over the years.
The impact-resistance lenses required by the U.S. Food and Drug Administration (FDA) in all eyeglasses and sunglasses supplied to the public after December 31, 1971 are not all shatter-proof or break-proof. Although impact-resistant lenses afford greater protection than previously provided, they don’t furnish an unbreakable shield against eye injury. The FDA regulation only asks that eyeglasses and sunglasses have heat-treated glass lenses, plastic lenses, laminated glass lenses or glass lenses made impact-resistant by other means. They must be capable of withstanding an impact test in which a 5/8-inch steel ball is dropped on the lens from a height of 50 inches. And the regulation does not cover contact lenses.
