ICD-10: F90.2

Attention-Deficit Hyperactivity Disorder (ADHD), Combined Type, classified under ICD-10 code F90.2, is a prevalent neurodevelopmental disorder characterized by a combination of symptoms related to inattention, hyperactivity, and impulsivity. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this diagnosis is crucial for effective identification and management.

Clinical Presentation

ADHD Combined Type is marked by the presence of both inattentive and hyperactive-impulsive symptoms. This dual presentation can significantly impact a patient's daily functioning, academic performance, and social interactions. The symptoms typically manifest in early childhood, often before the age of 12, and can persist into adolescence and adulthood.

Signs and Symptoms

1. Inattention:
   - Difficulty sustaining attention in tasks or play activities.
   - Frequent careless mistakes in schoolwork or other activities.
   - Difficulty organizing tasks and activities.
   - Avoidance or reluctance to engage in tasks that require sustained mental effort.
   - Frequently losing items necessary for tasks and activities (e.g., school materials, toys).
   - Easily distracted by extraneous stimuli.
   - Forgetfulness in daily activities.

2. Hyperactivity:
   - Fidgeting with hands or feet or squirming in seat.
   - Difficulty remaining seated in situations where it is expected.
   - Running or climbing in inappropriate situations.
   - Inability to play or engage in activities quietly.
   - Talking excessively.

3. Impulsivity:
   - Blurting out answers before questions have been completed.
   - Difficulty waiting for one’s turn.
   - Interrupting or intruding on others (e.g., butting into conversations or games).

Patient Characteristics

• Age of Onset: Symptoms typically appear before the age of 12, although they may be recognized later as the demands of school and social interactions increase.
• Gender: ADHD is more commonly diagnosed in boys than girls, although girls may present with more inattentive symptoms rather than hyperactive-impulsive ones.
• Comorbid Conditions: Many individuals with ADHD Combined Type may also experience comorbid conditions such as anxiety disorders, depression, learning disabilities, and oppositional defiant disorder (ODD) [4][5].
• Impact on Functioning: The symptoms can lead to significant impairment in social, academic, or occupational functioning. Children may struggle with peer relationships, academic performance, and family dynamics due to their symptoms [6][9].

Diagnosis and Assessment

The diagnosis of ADHD Combined Type is based on a comprehensive evaluation that includes clinical interviews, behavioral assessments, and standardized rating scales. The symptoms must be present in two or more settings (e.g., home, school) and must interfere with or reduce the quality of social, academic, or occupational functioning.

Diagnostic Criteria

According to the DSM-5, to meet the criteria for ADHD Combined Type, a patient must exhibit at least six symptoms of inattention and six symptoms of hyperactivity-impulsivity for at least six months, and these symptoms must be inappropriate for the developmental level of the individual [3][4].

Conclusion

ADHD Combined Type (ICD-10 code F90.2) is a complex disorder that requires careful assessment and a nuanced understanding of its clinical presentation. Recognizing the signs and symptoms, along with the characteristics of affected individuals, is essential for timely diagnosis and intervention. Early identification and appropriate management can significantly improve outcomes for individuals with ADHD, enhancing their ability to thrive in various aspects of life.

Attention-Deficit/Hyperactivity Disorder (ADHD), specifically the combined type classified under ICD-10 code F90.2, is characterized by a combination of symptoms related to inattention, hyperactivity, and impulsivity. The treatment approaches for this condition are multifaceted, often involving a combination of behavioral therapies, medication, and educational interventions. Below is a detailed overview of standard treatment approaches for ADHD, combined type.

Overview of ADHD Combined Type

ADHD, combined type, is diagnosed when an individual exhibits significant symptoms of both inattention and hyperactivity-impulsivity. This diagnosis is prevalent among children and can persist into adulthood, affecting academic performance, social interactions, and overall quality of life[1][2].

Standard Treatment Approaches

1. Medication Management

Medications are often a cornerstone of treatment for ADHD, particularly for the combined type. The primary classes of medications include:

• Stimulants: These are the most commonly prescribed medications for ADHD. They work by increasing the levels of certain neurotransmitters in the brain, which helps improve attention and reduce hyperactive behaviors. Common stimulant medications include:
• Methylphenidate (e.g., Ritalin, Concerta)

• Amphetamines (e.g., Adderall, Vyvanse)

• Non-Stimulants: For some patients, non-stimulant medications may be more appropriate, especially if they experience side effects from stimulants or have a history of substance abuse. Examples include:

• Atomoxetine (Strattera)
• Guanfacine (Intuniv)
• Clonidine (Kapvay)

Medication should be closely monitored by healthcare providers to assess effectiveness and manage any potential side effects[3][4].

2. Behavioral Therapy

Behavioral therapy is an essential component of ADHD treatment, particularly for children. This approach focuses on modifying specific behaviors through reinforcement strategies. Key elements include:

• Parent Training: Educating parents on effective behavior management techniques can significantly improve outcomes. This may involve setting clear expectations, using positive reinforcement, and implementing consistent consequences for behaviors.

• Cognitive Behavioral Therapy (CBT): This therapy helps individuals develop coping strategies and problem-solving skills. It can be particularly beneficial for older children and adolescents, helping them manage their symptoms and improve their self-esteem[5].

3. Psychoeducation

Psychoeducation involves educating the patient and their family about ADHD, its symptoms, and treatment options. Understanding the disorder can empower families to make informed decisions and foster a supportive environment for the individual with ADHD. This education often includes:

• Information about ADHD and its impact on daily life
• Strategies for managing symptoms at home and school
• Resources for additional support and advocacy[6].

4. School-Based Interventions

Educational support is crucial for children with ADHD. Schools can implement various strategies to help students succeed, including:

• Individualized Education Programs (IEPs) or 504 Plans: These plans provide accommodations tailored to the student's needs, such as extended time on tests, preferential seating, and modified assignments.

• Behavioral Interventions: Teachers can use behavior modification techniques, such as token economies or structured routines, to help manage classroom behavior and enhance learning[7].

5. Lifestyle Modifications

In addition to formal treatments, lifestyle changes can support overall well-being and symptom management. Recommendations include:

• Regular Physical Activity: Exercise has been shown to improve focus and reduce impulsivity in children with ADHD.

• Healthy Diet: A balanced diet rich in omega-3 fatty acids, fruits, vegetables, and whole grains can support brain health.

• Sleep Hygiene: Ensuring adequate sleep is crucial, as sleep deprivation can exacerbate ADHD symptoms[8].

Conclusion

The treatment of ADHD, combined type (ICD-10 code F90.2), requires a comprehensive approach that includes medication, behavioral therapy, psychoeducation, school-based interventions, and lifestyle modifications. Each treatment plan should be individualized, taking into account the specific needs and circumstances of the patient. Ongoing collaboration among healthcare providers, educators, and families is essential to optimize outcomes and support individuals with ADHD in achieving their full potential.
