As many symptoms are often put down to the menopause, depression, stress or simply aging, it can be tricky to catch Alzheimer’s in its early stages.
Former GMTV host Fiona Phillips recently revealed she has the disease at the relatively young age of 62 – initially thinking she was just suffering from brain fog and anxiety.
Although she believed the symptoms were the result of a particularly bad menopause, she was diagnosed with the illness - a brain disorder that slowly destroys memory and thinking skills - 18 months ago.
