Delirium is a medical condition which causes fatal disturbances in psychological and mental abilities. This results in reduced awareness and confused thinking. Alcohol withdrawal, surgery, infection, medication, changes in metabolic levels (low sodium content) and severe medical illness contribute in developing delirium.
Signs of delirium include inability to be focus on one thing, not responding to conversations or questions, being distracted by unimportant things, being withdrawn and detached. Symptoms of severe delirium include poor memory causing trouble in recollecting certain events, disorientation, difficulty in recalling words, rambling rubbish which doesn't make any sense, trouble writing and difficulty understanding speech.
Anxiety, depression and irritability can be early signs of delirium which usually goes unnoticed. Delirium can be caused due to a lot of factors such as drug toxicity, certain medications, drug abuse, low calcium, terminal illness, emotional distress and medications to treat Parkinson's disease.
You are more susceptible in developing delirium if you have brain disorders, if you are old, or if you have hearing or visual impairment and if you have multiple medical problems.
