There are different types of depression. Major depression is what you might typically think of as depression. You might also think of bipolar depression. The depression spectrum is the sort of continuum of different conditions with symptoms related to these conditions. Alternatively, we may call these mood disorders. Of course, we don’t love the word “disorder” since it inherently compares itself to some vague “normal.” But the sentiment is essentially that you have symptoms that interfere with your quality of life.
The Depression Spectrum Isn’t Linear
There are many different types of depression on the depression spectrum. We share some of those below. However, the spectrum isn’t linear. It’s not as though there’s one type of depression on the left and one on the right and a bunch in between.
Instead, there are overlapping symptoms and levels of severity. Each person may experience any type of depression at any level of severity. This may change for that individual with time.
Moreover, an individual may experience more than one type of depression either simultaneously or separately. In particular, people might have a dual diagnosis of major depression with one of the other types of depression such as persistent depressive disorder or substance-induced depression.
Types of Depression on The Depression Spectrum
Here are some of the types of depression that you’ll find on the spectrum:
Major depressive disorder
This is the most commonly recognized form of depression and involves persistent feelings of sadness, hopelessness, and loss of interest or pleasure in activities.
Dysthymia
Also known as persistent depressive disorder, this condition involves milder but longer-lasting symptoms of depression that can persist for years.
Seasonal affective disorder (SAD)
This is a type of depression that is linked to changes in the seasons, typically occurring in the fall and winter months when there is less sunlight. However, it can even occur in spring and summer.
Postpartum depression
This is a type of depression that occurs after giving birth and is thought to be linked to hormonal changes.
Bipolar disorder
This is a mood disorder that involves periods of depression alternating with periods of mania or hypomania, which are characterized by high energy levels, impulsivity, and racing thoughts.
Atypical depression
This form of depression involves symptoms such as excessive need for sleep, increased appetite, and weight gain. You might also find that your limbs feel heavy.
Psychotic depression
This is a severe form of depression that is characterized by hallucinations, delusions, and other symptoms of psychosis.
Situational depression
This is a temporary form of depression that occurs in response to a specific event, such as the loss of a loved one, a breakup, or a job loss. This might also be called an adjustment order with depressed mood.
Melancholic depression
This is a severe form of depression that is characterized by a loss of pleasure or interest in most activities, as well as physical symptoms such as insomnia, fatigue, and loss of appetite.
Catatonic depression
This is a rare and severe form of depression that can involve physical symptoms such as immobility, mutism, and rigidity.
Substance-induced depression
This is a type of depression that can occur as a result of substance use or withdrawal from drugs or alcohol.
Depression due to a medical condition
This is a type of depression that can occur as a result of a medical condition, such as Parkinson’s disease, stroke, or cancer.

Additional Information To Consider About Depression
Here are some other things that you might want to take into consideration in regards to the depression spectrum:
Depression in the elderly
While depression can affect individuals of all ages, it is often underdiagnosed and undertreated in older adults. This can be due in part to the fact that depressive symptoms may be attributed to other medical conditions or life changes, such as the loss of a spouse or the onset of a chronic illness.
Depression and cognitive decline
Some research suggests that depression may be a risk factor for cognitive decline and dementia in older adults. However, more research is needed to fully understand the link between depression and cognitive function.
Cultural differences
Cultural factors can play a role in the experience and expression of depression. For example, some cultures may place a greater emphasis on physical symptoms, while others may place more emphasis on emotional symptoms.
Depression in men
While depression is more commonly diagnosed in women, men can also experience depression. However, men may be less likely to seek treatment for depression due to societal norms that discourage men from expressing emotions or seeking help.
Postpartum depression in men
While postpartum depression is commonly associated with women, research suggests that men can also experience symptoms of depression after the birth of a child. This phenomenon, known as paternal postpartum depression, may be linked to changes in hormone levels and increased stress and responsibility.
Depression and chronic illness
Individuals with chronic illnesses, such as heart disease or diabetes, may be at increased risk for depression. Additionally, depression can worsen the symptoms and prognosis of certain chronic illnesses.
Depression and physical pain
Depression can be linked to physical symptoms such as pain, headaches, and gastrointestinal issues. This association may be due in part to the fact that depression can lead to changes in the body’s inflammatory response and affect pain processing in the brain.
Depression and creativity
While depression is often thought of as a debilitating condition, some research suggests that it may be linked to heightened creativity in some individuals. This association may be due in part to the fact that depression can lead individuals to engage in introspection and creative self-expression.
Depression and sleep
Depression can have a significant impact on sleep, with individuals experiencing symptoms such as insomnia or hypersomnia. Interestingly, some research suggests that treating sleep disturbances may also help to alleviate depressive symptoms.
Seasonal affective disorder (SAD) and light therapy
Light therapy, which involves exposure to bright, artificial light, is an effective treatment for SAD. This type of therapy is thought to work by regulating the body’s circadian rhythms and increasing serotonin levels.
