My dad is showing signs of dementia, he does not want to go to a psychiatric hospital for an assessment, what is the steps that we can take?

Medical assessment : Your father needs a medical assessment first as there are a variety of medical conditions that may result in altered consciousness. In case diagnosed with dementia, the overall plan of care becomes complex, it should include a local social worker in order to decide based on circumstances if his care can continue at home or he needs a long term facility specializing in such disorders.
