Early signs of senility, which are also symptoms of dementia and Alzheimer's Disease, include memory loss, difficulty planning or problem solving, changes in vision and confusion when grasping times and places, according to WebMD. Senility is also characterized by difficulty with word choice and completing daily tasks.
Senility may also cause individuals to lose objects regularly, experience a lapse in judgment that can lead to poor decisions and become socially withdrawn due to a lack of motivation, explains WebMD. Senile adults may have frequent mood changes that cause them to feel scared, anxious or depressed and get upset easily, especially when suspicious of other people. Following conversations can become more difficult, and senile adults may stop in the middle of a discussion when confused or forgetful. It is also common for senile individuals to repeat themselves because they may have forgotten that they are already shared information.
Someone with symptoms of senility, dementia or Alzheimer's Disease should consult a physician for an evaluation of mental and physical health, suggests WebMD. Medical professionals evaluate memory, thinking skills and problem-solving ability, and they may require brain imaging tests and blood work to diagnose the condition. Senile patients may be referred to neurologists who specialize in treating conditions of the nervous system and brain.
