What should b done hence forth to avoid more complication. And what can happen at worst

### output:

I carefully read your query, and I am sorry about your grandmothers' health issues. The diagnosis of bilateral infarction would justify her symptoms. A lacuna infarction is small but since you say frontoparietal meaning involving two lobes I guess there must be multiple ones. Those infarction have already happened now can't take them back, but you can reduce the risk of further ones in the future by treating hypertension and high cholesterol you mentioned as well as with aspirin. The risk of her having a stroke will remain significant but by these measures we can lower it. As for the atrophy if severe it could be a sign of dementia, meaning a fall in her higher mental functions like memory, speech, judgement, complex tasks, planning and organizing, etc., if that is a case it is a progressive disease which could progress for years and render the patient unable to take care of herself and immobilized in bed. But I'm saying that just because you asked for worse case scenario. At the moment there is no diagnosis of dementia if there are no higher mental signs you have noticed, it's not defined by atrophy, atrophy is an aging process which can be found also in old people without dementia. There are many types of dementia, most frequent is Alzheimer's disease, but if there is Parkinsonism syn Chat Doctor.  Regarding the treatment Pakistan is used to treat Parkinsonism tremor, but you should be careful in old people as at times it causes psychic symptoms like hallucinations, agitation. I hope to have been of help.
