case study

BACKGROUND

Katie is an 8 year old Caucasian female who is brought to your office today by her mother & father. They report that they were referred to you by their primary care provider after seeking her advice because Katie’s teacher suggested that she may have ADHD. Katie’s parents reported that their PCP felt that she should be evaluated by psychiatry to determine whether or not she has this condition. 

The parents give you a copy of a form titled “Conner’s Teacher Rating Scale-Revised”. This scale was filled out by Katie’s teacher and sent home to the parents so that they could share it with their family primary care provider. According to the scoring provided by her teacher, Katie is inattentive, easily distracted, forgets things she already learned, is poor in spelling, reading, and arithmetic. Her attention span is short, and she is noted to only pay attention to things she is interested in. The teacher opined that she lacks interest in school work and is easily distracted. Katie is also noted to start things but never finish them, and seldom follows through on instructions and fails to finish her school work. 

Katie’s parents actively deny that Katie has ADHD. “She would be running around like a wild person if she had ADHD” reports her mother. “She is never defiant or has temper outburst” adds her father.

SUBJECTIVE

Katie reports that she doesn’t know what the “big deal” is. She states that school is “OK”- her favorite subjects are “art” and “recess.” She states that she finds her other subjects boring, and sometimes hard because she feels “lost”. She admits that her mind does wander during class to things that she thinks of as more fun. “Sometimes” Katie reports “I will just be thinking about nothing and the teacher will call my name and I don’t know what they were talking about.” 

Katie reports that her home life is just fine. She reports that she loves her parents and that they are very good and kind to her. Denies any abuse, denies bullying at school. Offers no other concerns at this time.

Insight and judgment appear age appropriate. Katie denies any suicidal or homicidal ideation.

Diagnosis: Attention deficit hyperactivity disorder, predominantly inattentive presentation

 Decision Point One

Begin Ritalin (methylphenidate) chewable tablets 10 mg orally in the MORNING 

RESULTS OF DECISION POINT ONE

·   Client returns to clinic in four weeks

·   Katie’s parents report that they spoke with Katie’s teacher who notices that her symptoms are much better in the morning, which has resulted in improvement in her overall academic performance. However, by the afternoon, Katie is “staring off into space” and “daydreaming” again

·   Katie’s parents are very concerned, however, because Katie reported that her “heart felt funny.” You obtain a pulse rate and find that Katie’s heart is beating about 130 beats per minute

Decision Point Two

Change to Ritalin LA 20 mg orally daily in the MORNING 

RESULTS OF DECISION POINT TWO

·   Client returns to clinic in four weeks

·   Katie’s academic performance is still improved, and the switch to the LA preparation is lasting Katie throughout the school day

·   Katie’s reports of her heart feeling “funny” have gone away. Pulse was 92 during today’s office visit

Decision Point Three

Maintain current dose of Ritalin LA and reevaluate in 4 weeks

Guidance to Student

At this point, Katie’s symptoms are well controlled (her attention is sustained throughout the school day) and her side effects have gone away following change to a long-acting preparation. There is no indication at this point that the dose should be increased as it is always advisable to use the lowest effective dose of stimulant medication. Katie’s heart rate is appropriate for an 8 year old girl and an EKG would not be indicated based on her heart rate.
