A clinical form of depression with an onset in the late fall and remission in the spring; female:male ratio, 2:1.

Pathogenesis
Uncertain; reduced daily sunlight causes a drop in serotonin; PET scan data has linked depression to an increased in blood flow through the anterior limbic system, which may ultimately lead to hypoactivity; melatonin is decreased in women in summer and unchanged in men.
 
Management
Some SAD patients respond to high-intensity light, which alters the circadian rhythm, a therapy that is most effective in the morning; a light intensity of 10,000 lux viewed at close range may reset the biological clock.

Patient discussion about SAD

Q. I may be healthier now, but miserable… I’ve not been smoking for a whole month (my longest period in the last decade), and I do feel a bit better physically, but it seems that I lost the joy of life – I don’t go out with my friends any more (because they’re all smokers), I envy other smokers, and generally I feel nervous and dull. Will it be like that forever or is there hope?

A. Well, try to think about what are you missing? The foul smell? The yellow teeth? The feeling of suffocating next morning? Whenever you feel longing to cigarettes, try to think again why you stopped smoking- and it’d help you to keep with it.

Q. i get in to depression suddenly from a very calm mood. I get in to depression suddenly from a very calm mood. I am having a high mood swing for nearly a year. Sometimes I become crazy and start to jump on the roads. The other minute I do remember something from past and go in to deep depression. Due to this continuous change in my mood I am not able to concentrate on my studies. With this behavior I have lost some of my good friends too. This has put me in continuous stress and I have almost forgotten my good night sleep. My friends say that I am a bipolar….

A. Rohan,
The others are right, it would be benificial to you to seek professional help... You are saying that you have things in your past that are causing you stress, those things need to be worked through with a professional. You do not hve to continue suffering... Seek a proper diagnosis and you will get treatments that can help you feel much better...

Q. I’m often getting mood swings and depression. I’m fresher to my college. I’m often getting mood swings and depression. I don’t have close friend in this college, to share my thoughts. And I think there’s no point in life. And I don't want to do anything. Help me.

A. Well, depression and mood swings are common to all. So don’t worry about that. You need to talk to someone who is close to you and try to talk with your doctor, and a small amount of meds will help out a lot and won’t make you sick. Good luck!!!
