# Clinical Cases: Child and Adolescent Psychiatry

## Case 1: Attention-Deficit/Hyperactivity Disorder, Combined Presentation

### Patient Demographics
- **Age:** 8 years old
- **Sex:** Male
- **Grade:** 3rd grade

### Chief Complaint
Per mother: "His teacher says he can't sit still and won't pay attention. He's constantly in trouble at school."

### History of Present Illness
The patient is an 8-year-old boy brought by his mother for evaluation after repeated concerns from his teacher about behavior and academic performance. The teacher reports he is "constantly out of his seat," talks excessively, interrupts other students, and has difficulty completing assignments. He frequently loses homework and school supplies. His grades have dropped from A's and B's in first grade to C's and D's. He was recently placed on a behavior plan but has not improved.

At home, mother reports he has always been "high energy" but symptoms have worsened as academic demands increased. He cannot sit through dinner, often jumping up multiple times. He loses belongings regularly - jackets, toys, lunch boxes. He starts tasks but rarely finishes them, moving from one activity to another. He blurts out answers to questions before they're completed and has difficulty waiting his turn in games, leading to conflict with siblings and peers.

Mother notes symptoms have been present "since he could walk" but were attributed to him being "all boy." Symptoms are present in all settings - home, school, sports practices, church. He struggles to make and keep friends because he doesn't follow rules in games and is "too much" for other children.

Despite struggles, he is described as smart, creative, and enthusiastic when interested in a topic. He can focus on video games for extended periods (hyperfocus on preferred activities).

## Case 2: Autism Spectrum Disorder

### Patient Demographics
- **Age:** 4 years old
- **Sex:** Male
- **Grade:** Preschool

### Chief Complaint
Per parents: "He doesn't talk like other kids his age, and he doesn't seem interested in playing with other children."

### History of Present Illness
The patient is a 4-year-old boy brought by his parents after his preschool teacher recommended evaluation. The teacher noted he rarely interacts with peers, preferring to play alone and becoming very distressed when other children try to join his activities. His language is limited compared to classmates, and he often repeats phrases from TV shows rather than engaging in conversation.

Parents report concerns began around 18 months when he was not pointing to objects or responding to his name. His first words emerged at age 2, later than his older sibling. He currently speaks in short phrases but rarely initiates conversation. When he wants something, he often leads his parents by the hand to the desired object rather than asking verbally. He makes limited eye contact. He does not show objects to share interest (joint attention).

He has intense, focused interests in trains and ceiling fans. He can identify and name over 100 trains but has little interest in other toys. He lines up his trains in specific orders and becomes very upset if the order is changed. He flaps his hands when excited. He insists on sameness in daily routines - taking the same route to school, eating from the same plate. Transitions between activities are very difficult and often trigger tantrums.

He is sensitive to loud sounds (covers ears, becomes distressed) and has restricted food preferences, eating only about 5 foods (all similar textures).

### Developmental History
- Sat independently: 7 months
- Walked: 13 months
- First words: 24 months (delayed)
- Phrases: 36 months (delayed)

## Case 3: Major Depressive Disorder in Adolescence

### Patient Demographics
- **Age:** 15 years old
- **Sex:** Female
- **Grade:** 10th grade

### Chief Complaint
Per patient: "I don't know. My parents made me come." Per parents: "She's not herself. She's irritable, her grades dropped, and she stays in her room all the time."

### History of Present Illness
The patient is a 15-year-old female brought by her parents for evaluation of mood and behavior changes over the past 4 months. Previously an honor roll student and varsity volleyball player, she has shown declining function across multiple domains. Her grades dropped from A's and B's to C's and D's. She quit the volleyball team, stating "I just don't care anymore." She has withdrawn from friends, rarely responding to texts and declining all social invitations. She spends most of her time in her room, often sleeping.

Parents describe her as increasingly irritable, "snapping" at family members over minor issues and frequently arguing. She has stopped activities she previously enjoyed, including drawing and playing guitar. She complains of frequent headaches and stomachaches, leading to multiple school absences.

When interviewed alone, the patient tearfully admits she feels "empty" and "worthless." She reports persistent sad mood for most of the day, nearly every day, for over 3 months. She has difficulty concentrating on schoolwork ("I read the same page over and over"). She sleeps 12+ hours on weekends but still feels tired. Her appetite is decreased, and she has lost 8 pounds. She has passive suicidal ideation, stating "Sometimes I think everyone would be better off without me" but denies any plan, intent, or access to means. She has not engaged in self-harm.

She identifies a specific trigger: her best friend moved away at the start of the school year, and she has struggled to adjust. She also reports increasing conflict with her parents about grades and extracurriculars.

### Past Psychiatric History
- No prior psychiatric treatment
