While stimulants, clonidine, and guanfacine are commonly used to treat ADHD, antipsychotics are not typically the first-line choice for this disorder.

Clonidine is often used as a first-line medication for treating ODD, due to its effectiveness in reducing aggression and irritability.

SSRIs work by inhibiting the reuptake of serotonin, thereby increasing its availability in the synaptic cleft and enhancing serotonergic neurotransmission.

Stimulant medication can sometimes cause weight loss in children and adolescents, as it can suppress appetite and increase metabolism.

Mood stabilizers, such as lithium, valproate, and carbamazepine, are the primary medication class used to treat bipolar disorder in children and adolescents.

Long-term use of antipsychotic medication in children and adolescents can be associated with weight gain, increased risk of diabetes, and tardive dyskinesia, but it does not typically lead to improved cognitive function.

Atypical antipsychotics work primarily by blocking dopamine D2 receptors in the brain, reducing dopaminergic activity and alleviating psychotic symptoms.

TCAs can cause a variety of side effects in children and adolescents, including increased heart rate, dry mouth, constipation, and seizures.

Benzodiazepines work by potentiating the effects of GABA, an inhibitory neurotransmitter, in the brain, leading to a decrease in neuronal excitability and a calming effect.

Psychostimulants are typically well-tolerated and effective in improving attention and focus in children and adolescents with ADHD. They do not typically cause hallucinations.

Lithium works primarily by stabilizing neuronal membranes, reducing neuronal excitability, and preventing extreme mood swings in bipolar disorder.

Valproate can cause a variety of side effects in children and adolescents, including weight gain, increased risk of liver damage, and tremor.

Carbamazepine works primarily by stabilizing neuronal membranes, reducing neuronal excitability, and preventing extreme mood swings in bipolar disorder.

Risperidone can cause a variety of side effects in children and adolescents, including increased prolactin levels, weight gain, and sedation, but it does not typically lead to improved cognitive function.

Olanzapine works primarily by blocking dopamine D2 receptors in the brain, reducing dopaminergic activity and alleviating psychotic symptoms.
