Is depression a chemical imbalance in the brain?
The chemical imbalance theory is unproven and often cited as an explanation for mental health conditions. It states that these conditions are caused by an imbalance of neurotransmitters between nerve cells in the brain. For example, depression is said to be a result of having too little serotonin in the brain.
Can u inherit depression?
Depression is known to run in families, suggesting that genetic factors contribute to the risk of developing this disease. However, research into the genetics of depression is in its early stages, and very little is known for certain about the genetic basis of the disease.

What age does your IQ peak?
Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline.
Can anxiety and depression be passed down?
Anxiety and depression can still be genetic if they show up in your older family members. But often, new conditions in people that are over the age of 20 are linked to painful or stressful life events.

The prevalence of adults with a major depressive episode was highest among individuals aged 18-25 (13.1%).

What is the number one cause of depression?
Research suggests that depression doesn’t spring from simply having too much or too little of certain brain chemicals. Rather, there are many possible causes of depression, including faulty mood regulation by the brain, genetic vulnerability, stressful life events, medications, and medical problems.
Can Brain Scans See Depression?
The signs of depression aren’t obvious in a brain scan. But brain imaging can show blood flowing to different areas, and if it comes to two areas at the same time, a sign of “functional connectivity,” Liston said.
Can a chemical imbalance in the brain be cured?
Medication or pills can change your brain chemistry temporarily, but they have no power to change neural pathways or associations. There is no long-term cure for social anxiety in medication. There is a temporary, chemical change in your brain brought about by the medication.
