<s>[INST] My husband has been diagnosed with vascular dementia. He is being encouraged to keep up with his exercise which he does five days per week. What are the benefits of exercise for someone already suffering with moderate dementia? Can exercise help reverse or delay the progress of disease? [/INST] HIT hank for asking to ChatDoctorI really appreciate your concern for your husband you have not mentioned the age of your husband this could be helpful, if this is the dementia then exercise won't be helpful here the underlying cause is the matter if this is because of age then nothing can be done, some neurological conditions are there which gives better results with the medicine, like dementia due to TIA = Transient ischemic attack" hope this information helps you, have nice day. </s>
