There are many types of depression. The signs and symptoms of depression can be different depending on the type. Some of the signs of depression may be feelings of sadness, lack of interest in hobbies, excessive sleeping, moodiness, and even thoughts of suicide. Depression can interfere with a person's ability to work, sleep, eat, and enjoy everyday activities.
Major Depressive Disorder
Major depressive disorder is a depression that is daily and lasts for more than 2 weeks. Symptoms of major depressive disorders are feelings of being sad, lonely, lack of interest in hobbies, loss of energy, feelings of guilt or worthlessness, restlessness, weight loss or weight gain, and thoughts of suicide.
Chronic depression may possibly be related to the brain changes that involve serotonin. Serotonin is a chemical in the brain which helps your brain to cope with emotions. Signs of chronic depression are persistent sadness, sleeping problems, feelings of guilt, helplessness, hopelessness, or worthlessness, difficulty concentrating, thinking, or making decisions, persistent aches and pains, and thoughts of suicide.
Bipolar disorder is a complex genetic disorder involving mood swings. The mood swings can happen frequently ranging from mild to very extreme and can happen all of the sudden or come on gradually. People who are bipolar can have a hard time thinking, distorted perceptions of reality, and impaired social functioning. Symptoms of bipolar disorder are weight problems, difficulty concentrating, fatigue, feelings of guilt and pessimism, headaches, digestive disorders, irritability, and thoughts of suicide.
Atypical depression is caused by a chemical imbalance in the brain. Atypical depression symptoms are weight gain, excessive sleeping, feeling anxious, sadness, uncontrollable crying, headaches, decreased sex drive, loss of energy, difficulty concentrating, increased reaction to rejection, thoughts of death or suicide, and attempting suicide.
Seasonal depression will start and end the same time each year. The most common type of seasonal depression is "winter depression". The fact that there is less sunlight in the winter may be part of the cause. With less sunlight the brain does not produce enough serotonin. Symptoms of seasonal depression are increased need for sleep, increased appetite, weight gain, irritability, relationship problems, and a feeling of heaviness in the arms and legs.
Psychotic depression happens when a severe depressive illness has a co-existing form of psychosis. People with psychotic depression may have hallucinations along with other symptoms such as feeling hopeless, worthless, and helpless. People suffering from this type of depression may get angry for no reason or neglect their appearance by not bathing or changing their clothes.
Postpartum depression is linked to chemical, social, and physiological changes after having a baby. Postpartum depression usually starts about 4 weeks after having a baby. The symptoms include lack of sleep, appetite changes, fatigue, decreased libido, mood changes, feelings of worthlessness, hopelessness, and thoughts of suicide.
