A 25-year-old female pharmaceutical sales representative presents to the PMHNP for an evaluation due to what she calls an increasing level of anxiety about her job, which she has had for approximately 1 year. She works from a home office, and it has become unorganized and cluttered. She frequently forgets deadlines for submitting reports, and as a result she turns them in at the last minute. She has been chastised more than once by her boss for not paying attention to details on these necessary reports. Because she does not report to anyone on a day-to-day basis, she often gets completely overwhelmed by the autonomy of the job, and as a result she completely "shuts down." She knows she should be planning her time better, but she has never been good at time management or planning. During her evaluation, she reports making excellent grades until she got to college. She says she can remember not being able to pay attention to teachers as early as first grade, and her report cards frequently said she talked too much. She often got in trouble at home for not finishing chores because she was easily distracted and forgetful. Today, she says she is getting so overwhelmed and anxious about her job performance that she is thinking about quitting. She says her friends are tired of her complaining and tell her she has it "so good." She wishes someone would just tell her exactly what to do every day so she didn't have to think about anything.

Choice A reason: Generalized anxiety disorder involves persistent, excessive worry about multiple areas of life but does not explain the chronic pattern of inattention, disorganization, and impulsivity beginning in childhood.

Choice B reason: Attention deficit hyperactivity disorder (ADHD), particularly the inattentive subtype, is characterized by difficulty sustaining attention, disorganization, forgetfulness, and chronic performance issues starting in childhood, consistent with this patient’s history.

Choice C reason: Specific learning disorders primarily involve difficulties with academic skills such as reading, writing, or math, rather than pervasive attentional and executive functioning problems.

Choice D reason: Bipolar disorder involves episodic mood changes, such as mania or depression, rather than persistent inattention and executive dysfunction across the lifespan.
