Attention Deficit Hyperactivity Disorder

 

Symptoms must be present prior to age 7, last longer than 6 months, and impair functioning to receive the diagnosis. For children, this generally means difficulty achieving or maintaining appropriate behavior in school. Boys are often referred at an earlier age due to hyperactivity; Girls are often “silent sufferers” because they have less hyperactivity or impulsivity and go unrecognized. Must consider developmental levels in making the diagnosis (e.g., differentiating normal activity levels). It was once felt that all children  outgrow ADHD by adolescence, however we now know that approximately 50% continue to evidence symptoms into adulthood.

Medications Commonly Used To Treat Attention Deficit Hyperactivity Disorder

 

 

Psychostimulant Medications

 

 

Short Acting                                                       Long Acting

 

Ritalin                                                                                      Ritalin LA

Mechanisms of Action

 

¨     Short acting forms begin working in 20 minutes and last 3 – 4 hours. Short acting forms are used when appetite and weight gain are an issue They have the added stigma of children having to leave class to take the medication, they have to be dosed multiple times a day, and symptoms of ADHD increase as medications are wearing off and prior to the next dose (e.g. kids are often under-medicated during the last class before lunch, cafeteria time, and last class of the day).

¨     Long acting forms begin working in 20 minutes and last throughout school and homework time/afterschool program (8 – 12 hours). They are gradually released over time and you avoid the peaks and lows. The downside is that kids will have a very poor appetite for the entire time that the medication is in their system.

 

Side Effects

 

¨     Appetite suppression

¨     Growth suppression

¨     Increased Blood Pressure

¨     Rebound irritability: occurs when the medication is wearing off. More likely to occur with short acting forms; Includes crying, irritability, personality changes, and clingy behavior.

¨     Tics: may be “unmasked” in children who are at risk.

¨     Headaches: usually only within the first week, responds to aspirin.

¨     Stomachache: if taken on an empty stomach.

¨     Cylert may cause fatal liver problems

Major Depression

 

      The average age of onset is in the mid-20’s, however the age has been decreasing over the past decade. The lifetime is 10-25% in females and 5-12% in males. Depression is twice as common in adolescent and adult females than males, however pre-pubertal rates are equal in boys and girls. Most episodes recover within a year but 60% of people who have experienced one episode of depression will have another episode in their lifetime. Depression affects health status with more people experiencing pain and physical illness. Up to 15% of individuals with severe depression successfully complete suicide. To receive the diagnosis 5 or more of the following symptoms must be present for at least 2 weeks, and symptoms must impair functioning.

Bipolar Disorder

 

            The lifetime prevalence of Bipolar Disorder is 0.4 to 1.6%. Average age of onset is 20. Disorder is equally common in men and women, though the first episode is more likely to be depression in women and mania in men. Individuals must have at least one episode of depression lasting at least 2 weeks and one episode of mania lasting at least a week to meet criteria. The first manic episode may emerge as a result of antidepressant treatment. Children often present as “rapid cyclers”. Approx. 95% of children with the disorder have a pre-morbid history of ADHD. There is a high co-morbidity with drugs and alcohol, and completed suicide occurs in 10-15% of cases. DSM-IV includes types I and II; DSM V may include Types I-VI.

Obsessive-Compulsive Disorder (OCD)

 

 

Prevalence rates of 1 to 2.3% in children. Childhood onset occurs more frequently and earlier in males (age 6-15) than females (age 20-29). There is a high association with Learning Disorders, Disruptive Behavior Disorders, and body concerns in children. A subset of children develop acute pre-pubertal symptoms associated with Streptococcal infections. 20-30% have a current or past history of tics. Children must engage in the symptoms for greater than one hour a day, and are not required to experience symptoms as ego-dystonic (as in adults). Symptoms are more likely to present themselves at home than in public. The course is “waxing and waning”, with symptoms remitting and changing over time.

 

 

 

Obsessions

 

¨     Recurrent, intrusive thoughts, images or impulses that are not merely everyday worries or concerns

¨     Person attempts to ignore or suppress the thoughts (ego-dystonic)

¨     Behaviors are aimed at reducing distressing or to avoid a dreaded event or situation

¨     Most common compulsions involve washing and cleaning, counting, checking, requesting or demanding reassurances, repeating actions, and ordering

¨     Marked and persistent fear of one or more social or performance situations

¨     Person fears humiliation or embarrassment

¨     Must include fear of age-appropriate relationships in children

¨     Exposure to the situation causes increased anxiety or panic symptoms (may include crying, tantrums, or “freezing”
