Many people think of depression as simply feeling sad, but it is a much more complex medical condition and every patient’s experience of it is different.
Part of what makes depression complex is that people with the condition experience multiple symptoms.
Depression can include emotional, physical and cognitive symptoms.
The emotional symptoms such as sadness, feelings of hopelessness and anxiety are perhaps those traditionally most associated with depression.
Physical symptoms of depression are wide ranging and can involve problems with sleep, appetite and weight, sexual dysfunction and headaches.
Cognitive symptoms affect attention, memory, and decision-making, which can have negative consequences on daily functioning, affecting work or educational performance.
