A noticeable decrease in a child's energy can be a telltale sign that something is just "not right." In fact, lack of energy and always feeling tired are sometimes symptoms of childhood depression.
Lack of Energy
Children with depression are likely to lack energy on all or most days. They may lack motivation for almost anything – sometimes for even eating or bathing.
Why Depression Slows Children Down
Researchers have identified several theories for why children with depression often feel so tired and unmotivated:
- Insomnia, or difficulty with falling or staying sleep, is common in depressed children. Insomnia often leads to daytime sleepiness because of missed sleep. As a result a child may have problems with concentration and irritability.
- Neurotransmitter chemicals like, serotonin, are thought to be abnormally low in children with depression. Serotonin plays an important part of regulating a child’s sleep cycles, motivation, and activity level. Given this, many depression medications increase levels of serotonin and relieve depression symptoms in children.
- Hopelessness is another unfortunate symptom of depression in children. Hopelessness causes children to feel that their lives and futures are out of control. Often a hopeless child gives up trying to do almost anything and believes that her efforts are ineffective.
How to Help
If your child is suddenly lacking energy or tired very often talk to her pediatrician.
There are many reasons why a child might lack energy or be tired, like illness or a change in routine. A physician can rule out underlying medical illness and determine if your child needs to be evaluated further for depression.
Helping your child get appropriate treatment for her depression helps ensure that her childhood is full of energy and joy.
