With some causes of dementia, curing the underlying condition isn't possible, and so dementia treatment focuses on easing the symptoms. This can help reduce distress and disruption for the caregiver as well as the patient. Different types of drug treatments, of course, apply to different categories of symptoms:
To climb stairs, place your cane in the hand opposite your injured leg. With your free hand, grasp the handrail. Step up on your good leg first, then step up on the injured leg. To come down stairs, put your cane on the step first, then your injured leg and then, finally, your good leg, which carries your body weight.
Bend your knee back in (try not to lower leg in between repetitions if possible). That's one rep. Do up to 3 sets of 15 repetitions on each leg, switching sides after each set. If this is too tough, try lowering your leg for the kick and/or holding onto a chair or wall with your right hand to help keep your balance.
