Hello, My dad got 2 vertical lines on his forehead and head which makes me feel worry. It happened gradually over a year. He is 70 and he also starts forgetting things even words. It s not that serious but because we had relatives (my dad s uncle) who got alzimer , I don t want the same happen to my dad and try to prevent it as much as possible. Can you please advise me on this? I can attach a photo but couldn t find the place to attach it.
