My 68 year old father said to my mum and I that a television presenter looks at him for real, he said it started happening around 6 months ago, its gotten to the point that my dad has to leave the bedroom to change somewhere else because he thinks the people and especially the television presenter will see him change clothes, i am worried about my dad, do you know what kind of thing he mightt be going through or suffering from,? Is it ahlzeimers/mental disorder/ or something else? He is lately showing sign of forgetting alotof things like peoples names , not understanding who my mum is talking about and its a person we regularly see, not answering a question logically etc. your help would be much appreciated, i just want to get advice to see what kind of health professional i can refer him to see. Thankyou
