My mom passed away at age 50 of early-onset alzheimer’s disease, she was diagnosed with it about 4 years prior to her death but was evident that it had been affecting her for quite awhile before that. They said it was a rare form of dementia and probably inherited. My grandmothers, both my mom’s mom and my dad’s mom, were diagnosed with alzheimer’s disease. What are my chances of getting alzheimer’s disease? Also, I’m female and I read somewhere that more females contract alzheimer’s than males, but I’m not sure if that’s true.
