Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. Dementia is a broad category of brain diseases that includes any disease that causes loss of cognitive ability (the ability to think and reason clearly) that is severe enough to affect a person s daily functioning. It must also be a worsening of functioning compared to how the person was previously. The most common form of dementia is Alzheimer s disease. Other common forms of dementia include: Lewy body dementia, vascular dementia, frontotemporal dementia, progressive supranuclear palsy, corticobasal degeneration, normal pressure hydrocephalus and Creutzfeldt–Jakob disease. But whatever may be the form of dementia, hair cut is not related to the form, it is related to the patient. You and your people know the patient better than we here. You must have tried all conventional methods. A visit to the hairdresser, or a hairdresser coming to the house may be a better alternative. Many people with dementia continue to enjoy having their hair cut and styled and this can continue to be a pleasurable experience. It is like feeding a 2 year old child. You do so many roles to make the child eat. Discover some role and act it out and do the haircut. Hope this answers your query. Available for further clarifications. Good luck.
