Growing Old and Issues of Diminished Capacity
The law assumes that adult individuals have mental capacity, that is, they are capable of making rational decisions on their own behalf. Note we say they are “capable” of making rational decisions. The law doesn’t expect or require that they actually make rational decisions. Competent individuals of all ages, old and young, have the right to make foolish, eccentric or idiosyncratic decisions. For better or worse, all of us are free to make bad decisions.
People Vary
A persons’s capacity may change from day to day (or even during the day), depending on the course of the illness, fatigue and the effects of medication. Some folks have good days and bad days. Some are more alert in the morning; some have their best time in the afternoon. Legal competency is not something that a person either has or doesn’t have –it can be quite variable.
Standards Vary
Whether or not a person is legally competent depends on the purpose for which the capacity is being determined. The law provides a different standard of competency for 1) making contracts, 2) making wills, 3) having a guardian appointed, 4) and giving informed consent to medical treatment.
Whether or not a person is competent is a legal determination, not a medical one. Medical testimony is important, and is always sought by a court in making the determination of capacity. Since the law has many different defined standards depending on the action being taken, the determination of whether or not a person is competent to do a certain thing is always a legal decision.
Lowest Standard
What surprises most people is that the capacity to make a will, called testamentary capacity, is the lowest level of capacity in the law. All that is required is that the person making the will (1) understand in a general away, the nature of his property, (2) knows who are the “natural objects of his bounty,” that is, the persons who would normally be his heirs, and (3) must be able to comprehend that he or she is making a will.
A person who has had a stroke, or is diagnosed with Alzheimer’s disease, may still have sufficient capacity to make a will even though there is some impairment of speech, some impairment of thought processes, and/or some physical impairment. The fact that a client does not know the year or the name of the President does not necessarily mean that she can not make a will. Since signing a will does not require a great deal of capacity, the fact that the next day the person does not remember the signing of a will does not invalidate the will if he had the minimum required capacity the day before when he signed it.

Maggie Kuhn started the Gray Panthers in 1970 as a response to her forced retirement at age 65. The mission of the Gray Panthers was to speak out against age discrimination, the Viet Nam war, and other political oppressions. There is no doubt that stereotyping due to age exists in contemporary society. The Gray Panthers call this kind of discrimination “ageism.” To be told "you’re too old" is as disheartening as to be told "you’re too young"; both statements make you a stereotype when in fact you are an individual. 
The issues surrounding diminished capacity run from whether or not an older adult should contihnue to drive, to whether he or she can live alone at home, wheter he or she can make a will, make gifts, and otherwise control finances, to whether or not a court-appointed guardian must be appointed. Often, a family’s first encounter with this question is whether or not the older adult should continue driving a car.
