The first signs of Alzheimer’s disease besides loss of memory are difficulties to find the right words, to express oneself and to understand others. Time and date perception is also challenging. Eventually the person has a hard time to orient in their surroundings, to read, write, calculate or manage practical things. Some patients have perception complications and cannot recognize what they see. Planning and reasoning becomes problematic.
The symptoms can vary between individuals and they progress gradually, which makes the onset of the disease hard to determine.
