In some cases, individuals feel anxious constantly or have severe episodes of anxiety, without there being any real danger or risk, and these symptoms interfere with general daily functioning; these presentations can sometimes be referred to as anxiety disorders. Research indicates that the prevalence for different anxiety disorders in children vary between 1-8%, some say 15-20%. As with Depression, most children and young people do not ask for help.
It is important to treat anxiety disorders early, because it is likely to become more difficult to treat, the longer you wait and the prognosis deteriorates. Anxiety disorders usually do not resolve on their own.
What are some of the signs of anxiety disorders?
Physical (health/medical) symptoms
Presentation usually relate to autonomic symptoms and motor tension, for example:
Increased respiration, heart rate, palpitations (awareness of heart beating), shortness of breath, dizziness
Epigastric (stomach) and chest pain, sweating, blushing, dry mouth, feeling of being 'choked'
Frequency (urinating often), urgency (feeling you 'have to go' urgently)
Nausea, diarrhoea, constipation, lack of appetite, insomnia, poor concentration, impulsive behaviour
Muscle tightening, fidgeting, hyperactivity, headaches and tremors (shaking)
Psychological symptoms
Avoiding the situation that causes stress or rapidly exiting rapidly from a scary situation
Anticipatory anxiety or constant worry / apprehension or heightened startle response
Feeling you are going 'crazy', 'mad' or going to die or that you, your life or 'things' are unreal
Fear of losing control or feeling you are losing control
Daydreams of scary memories, nightmares and flashbacks - reliving past events as if real
Detachment, emotional numbness or no interest in social interaction, relationships or previous interests
Not enjoying things you previously found enjoyable
What causes anxiety disorders or excessive anxiety?
The causes are often complex and a direct cause is not always clear. It is often helpful to consider predisposing, precipitating and maintaining risk factors as well as protective factors.
Protective factors:
This list will not prevent anxiety disorders completely, but will lower the risk and improve prognosis.
Engagement in enjoyable and regular group activities with friends or adults with similar interests
Many interests that are enjoyed regularly such as horse riding, swimming, boxing or cooking
Positive and supportive relationships with other children or young people, adults and family
Positive and supportive environment at home, at school and/or in the community
Certain personality traits (not taking life too seriously, not being too hard on yourself)
Good coping or defense mechanisms (sports, humour, friends)
This list is not comprehensive.
Risk factors:
Genetic factors (family history of mental illness or anxiety)
Certain personality traits (sensitive, anxious, needing to get things 'just right', hard on oneself)
Medical problems, illness or disorders
Social environment at home, at school and/or in the community
Major life events and trauma including traumatic events during early childhood and early adulthood
Stressors - chronic (such as bulling at school) and acute (death in the family or sudden change)
Other existing mental health difficulties e.g. Depression or neurodevelopmental problems e.g. ADHD
This list is not comprehensive.
Medical problems and medications that can cause anxiety symptoms:
Trauma, toxins (such as mercury) or nutrition deficiencies (such as Vit B12)
Infections especially chronic infections
Inflammatory disease (such as related to Lupus Erythematosus)
Neurological causes such as migraine or epilepsy (remember not all epilepsy presents with convulsions)
Cardiovascular or cardiopulmonary causes
Endocrine causes (such as related to adrenal or pituitary gland, thyroid, or parathyroid hormone)
Biochemical and haematological causes (such as relating to glucose levels and anaemia)
Neoplasms (some tumours produce adrenaline)
Medications (such as some antibiotics, sympathomimetics and vasopressors)
This list is not comprehensive.
Many medical disorders or side effects of medications can cause anxiety symptoms and look like anxiety disorders in children and young people where no anxiety disorders exist (differential diagnoses). Child Psychiatrists are medical doctors, so should be able to advise you and liaise with your GP to ensure that medical causes are excluded, before mental health causes are considered.
How are anxiety disorders diagnosed?
Child Psychiatrists meet with children with various degrees of anxiety every day. Many children present with anxiety, but no anxiety disorder. Many medical disorders and mental illness or neurodevelopmental disorders can present similar to anxiety disorders. Through a detailed assessment, including a psycho-social history, it becomes clear whether a diagnosis of a anxiety disorder is appropriate.
Differential Diagnoses (problem that can look similar to anxiety disorders in children):
Mood disorders such as Depression or Bipolar Disorder
Psychotic disorders such as Schizophrenia
Developmental disorders and neurodevelopmental disorders such as ADHD and Autism Spectrum Disorder
Adjustment and Separation Disorder
Abuse and attachment disorders, difficulties
This list is not comprehensive.
It is also important to know that different anxiety disorders can also look alike in children and young people (be differential diagnoses). Anxiety disorders such as PTSD or OCD in children often present rather different to the disorders in adults and assessment and diagnosis can be complex.
Comorbidities:
Children with anxiety disorders are more vulnerable to develop other mental health problems (complications) sometimes present with comorbidities (two or more disorders presenting together).
Child Psychiatrists assess for comorbidities that can occur with anxiety or anxiety disorders such as:
Depression (up to 30%)
Tic disorders (up to 30%)
ADHD (up to 10%)
Specific developmental disabilities or problems (24%)
Other anxiety disorders (up to 20%)
Enuresis and encopresis (more or less 4%)
This list is not comprehensive.
How are anxiety disorders treated?
Early treatment is essential and directly related to outcome or prognosis. It is essential to ensure that the diagnosis is accurate and that possible medical causes as well as mental health comorbidities and complications have been considered.
Comprehensive treatment packages (psychotherapy, family therapy or support, liaison with Education and social intervention with or without medication), tailored to individuals unique needs, are most often required.
Management/treatment recommendations may include medication (usually SSRIs such as Fluoxetine), but will almost certainly always include recommendations of social intervention and therapeutic intervention.
Individual therapy, such as Cognitive Behavioural Therapy (CBT) can be offered. This can give children and young people the opportunity to discuss worries, think about strategies to manage anxiety and learn tools to manage anxiety. Family work is also often helpful. Type of therapeutic intervention is usually related to presentation, personalty and temperament as well as patient preference. Some children and adults presenting with anxiety disorders or anxiety enjoy and respond well to CBT, others do not. Your specialist will be able to advise you.
Therapeutic options often helpful for Anxiety Disorders (and Depression) include cognitive behavioural therapy (CBT), cognitive analytical therapy (CAT), psychodynamic therapy, creative therapies, group therapy and systemic family therapy. Therapy usually last between 6-8 weeks (such as CBT) or longer. Therapy sessions are usually scheduled to last 45 minutes.
Social intervention is almost always an essential component of treatment and recommendations may vary. Most specialists agree that regular normative, enjoyable, meaningful, physical and non-physical activities after school hours with non-delinquent peers and adults with similar interests, offer children the opportunity to learn new skills, experience a sense of achievement and develop from an emotional, social, cognitive and physical point of view. Environment in the community, at school, work or at home is also relevant.
Practical and social recommendations may appear like simple solutions, but can inspire, support or maintain positive outcomes. An example - We were asked to assess the mental health of 100 unaccompanied minors; most witnessed their loved ones tortured and killed, and were tortured and enslaved themselves. Some children presented with anxiety disorders, including PTSD, and some children presented with Depression and PTSD. Most children were treated/managed through practical/social intervention, not medication, and positive outcomes were identified in more than 95% of the children. Less that 10% of children were started on medication. The practical intervention included connecting children to religious leaders (as they requested), community elders, employment or education opportunities (also as they requested). Many individuals who have experienced significant trauma say that the most helpful part of treatment was, having a 'safe space' where they could talk (or not talk) with someone that they 'connected' with, being busy (with what they enjoyed, with their goals) and having a sense of belonging (being welcomed in the community and feeling accepted).
Risk assessment, along with assessing for comorbidities and complications, throughout treatment or follow up, remain essential in all follow up appointments in mental health.
Medication may be indicated if psychological therapies fail, when impairment and distress are disabling (usually when children or young people are unable to engage in therapy) or when children or young people refuse to engage in therapy. Please see Depression for more information on SSRI's (medication often used for anxiety disorders).
Most psychiatrists absolutely avoid sedatives or tranquillisers, such as diazepam, and other serious medication such as beta blockers for anxiety disorders or panic in adults and especially in children and young people in the community, because the possible benefits very seldom outweighs the possible risks. Sedatives and tranquillisers can lead to significant rebound anxiety, dependence in a short period of time, and can interfere significantly with therapeutic progress and prognosis. Beta blockers can have significant cardiac side-effects and can significantly affect mood. The medication of choice to treat anxiety disorders is antidepressant medication, such as Fluoxetine (SSRI).
