Differential Diagnosis for KN

Single Most Likely Diagnosis

• Autism Spectrum Disorder (ASD): Given KN's existing diagnosis of autism, her history of responding well to structured academic environments, and her difficulties with executive functions, compulsions, and perfectionism, ASD remains a primary consideration. Her struggles with social interactions, such as feeling disrespected and expecting similar encouragement in other lab jobs, also align with ASD characteristics.

Other Likely Diagnoses

• Anxiety Disorder: KN's perfectionism and compulsions, which take up a significant amount of time, could be indicative of an anxiety disorder, such as Obsessive-Compulsive Disorder (OCD). Her reaction to being corrected for an error not her fault, leading to her leaving a job, suggests anxiety related to criticism or failure.
• Depressive Disorder: The loss of interest in planning her future, not wanting to engage in activities that are not fun or challenging, and her recent job change could be symptoms of a depressive disorder. Individuals with ASD are at a higher risk for developing depression.
• Attention Deficit Hyperactivity Disorder (ADHD): Executive function impairments, which KN experiences, are common in both ASD and ADHD. Her difficulty with planning and her desire for autonomy and challenging tasks might also suggest ADHD, particularly if she has symptoms of inattention or hyperactivity.

Do Not Miss Diagnoses

• Post-Traumatic Stress Disorder (PTSD): Although less likely, it's crucial not to miss PTSD, especially given KN's strong reaction to feeling disrespected. If the incident at her previous job or other unmentioned traumatic events have significantly impacted her, PTSD could be a consideration.
• Bipolar Disorder: The possibility of mood swings or episodes of depression and mania, which could be masked by her ASD or other conditions, makes bipolar disorder a "do not miss" diagnosis. Her high energy and engagement in challenging tasks could potentially be manic or hypomanic episodes.

Rare Diagnoses

• Savant Syndrome: Given KN's exceptional abilities in academics and her specific interests, Savant Syndrome could be considered, although it is rare. This condition is characterized by exceptional skills in areas such as mathematics, memory, or art, often in the context of ASD.
• Pathological Demand Avoidance (PDA): A subtype of ASD, PDA is characterized by an intense need for control and an avoidance of everyday demands. KN's desire for autonomy and her reaction to being corrected could align with PDA, but more specific criteria would need to be met for this diagnosis.
