Low mood in children

Overview

Low mood in children is when a child feels sad, down, or irritable for a period of time. It is different from normal ups and downs, as it lasts longer and affects how they enjoy life, play, learn, and get along with others. It can be a temporary response to a difficult event, but if it persists, it may be a sign of depression.

Yes, low mood is common in children. Many children feel sad or down from time to time, especially during difficult life events. When these feelings last for weeks or months and interfere with daily life, it may be a sign of depression.

Low mood can affect children of all ages, from young children to teenagers. It is more common in children who have experienced stress, trauma, or family problems. Girls are more likely to report low mood, but it affects boys too.

Symptoms

Common symptoms

• Feeling sad, empty, or hopeless most of the time
• Loss of interest in activities they used to enjoy
• Changes in appetite – eating too much or too little
• Sleep problems – sleeping too much or too little, or having trouble falling asleep
• Low energy or feeling tired all the time
• Trouble concentrating or making decisions
• Feeling worthless or guilty
• Thoughts about death or suicide (urgent – seek help immediately)

Symptoms in children

• Irritability, anger, or moodiness
• Withdrawing from friends and family
• Frequent physical complaints like headaches or stomach aches
• Changes in school performance or refusal to go to school
• Clinginess or separation anxiety in younger children
• Talking about feeling bad or being a failure

Symptoms in older adults

• In older adults, low mood may be mistaken for dementia or normal aging. Symptoms can include memory problems, social withdrawal, loss of appetite, and physical aches. But this article is about children, so this section is not directly relevant.

Causes

Main causes

• Stressful life events, such as moving home, parental divorce, or the death of a loved one
• Being bullied or having problems with friends
• School pressure or learning difficulties
• Family conflict or problems at home
• Hormonal changes during puberty

Risk factors

• Having a family history of depression or anxiety
• Experiencing trauma or abuse
• Having a chronic illness or disability
• Social isolation or lack of supportive relationships
• Low self-esteem or negative thinking patterns

When to see a doctor

See a doctor urgently if:

• If your child talks about suicide or self-harm, or shows dangerous behavior
• If your child stops eating or drinking for an extended time
• If your child refuses to leave their room or interact with anyone for several days

Book a routine appointment if:

• If your child has been feeling down for more than two weeks and it is affecting their daily life (school, friendships, eating, sleeping)
• If you notice a big change in your child's mood or behavior that does not improve
• If your child is struggling to cope with a difficult event and you are concerned

Diagnosis

A doctor or mental health professional will talk with you and your child to understand their feelings, how long they have been happening, and how they affect daily life. There is no lab test – the diagnosis is made through conversation and questionnaires.

Tests that may be done

• A detailed discussion about symptoms, thoughts, and feelings
• Physical examination to rule out other health problems (like thyroid issues)
• Sometimes questionnaires for you and your child to fill out

What to expect at your appointment

The doctor will ask questions in a friendly and reassuring way. They may also talk to your child alone for a short time. It is important to be honest so the doctor can give the best advice. The appointment may take 30 minutes to an hour.

Treatment

Treatment for low mood in children usually starts with talking therapies and support from family and school. In some cases, medication may be used, but only under specialist guidance. The goal is to help the child understand their feelings and build coping skills.

Self-care at home

• Make sure your child gets enough sleep – stick to a regular bedtime
• Encourage physical activity – even a walk or bike ride can boost mood
• Spend quality time together – doing something fun or just talking
• Help your child eat a balanced diet – limit sugary snacks and drinks
• Create a routine that includes time for homework, play, and rest

Medical treatments

Talking therapies, such as cognitive behavioural therapy (CBT), are often the first treatment. A therapist helps the child learn to change negative thoughts and behaviours. For some children, if therapy alone does not help, a doctor may consider medication. This is always started by a child psychiatrist or paediatrician and closely monitored. No specific drugs or doses are listed here.

When is surgery considered?

Surgery is not used for low mood or depression.

Living with this condition

Living with low mood can be hard for both the child and the family. The child may need extra patience and encouragement. It helps to keep a consistent daily routine, including time for rest, hobbies, and social activities. Celebrate small successes and be kind to yourself as a parent.

Lifestyle tips

• Encourage your child to stay connected with friends and family
• Limit screen time, especially before bed
• Help your child find a hobby or activity they enjoy
• Model healthy ways of dealing with stress

Diet and exercise

A balanced diet with plenty of fruits, vegetables, and whole grains can help support mood. Regular exercise, such as playing outside, dancing, or sports, can release feel-good chemicals in the brain. Aim for at least 60 minutes of physical activity a day for children.

Mental health and emotional wellbeing

Low mood can affect a child's self-esteem, school performance, and relationships. With support, most children recover fully. It is important to watch for worsening symptoms and to talk openly about feelings. If your child talks about suicide or self-harm, get help immediately.

Prevention

Not all low mood can be prevented, but you can lower the risk by creating a supportive, loving environment at home. Encourage open communication, teach your child coping skills, and address problems early. Building resilience – the ability to bounce back from setbacks – is key.

Vaccines

There are no vaccines for low mood or depression.

Screening programmes

There is no routine screening for low mood in all children. However, doctors may screen if they notice signs or if you raise concerns. If your child is at higher risk (such as after a trauma), your doctor may suggest regular check-ins. If you are worried, ask for an assessment.

Complications

If left untreated

• Low mood can lead to depression, which can affect school, friendships, and family life
• It can increase the risk of self-harm or suicidal thoughts
• It may cause long-term problems with relationships and emotional health

Long-term outlook

Most children with low mood get better with the right help. Treatment – especially talking therapies – is very effective. The earlier you get support, the better the outcome. With patience, love, and professional guidance, children can learn to manage their emotions and enjoy a happy, healthy life.
