"The different sorts of madness are innumerable." ~ Avicenna (Ibn Sina)
All of what is now-adays called modern medicine would not exist without the ground-work of Islamic scholars and scientists. This also true for mental health assessments, treatments and ongoing care. Beyond the common stereotype that Muslims are superstitious and believe that mental health problems are caused by Jinn (spirits made of smokeless fire), stands a well documented history of Islamic scholars and medical practisioners assessing illnesses, diagnosing them through identifying common symptoms and finding individual treatments and cures for patients.
