Assess the case of Mr. T.J., a 65-year-old male presenting with irritability, anger, verbal outbursts, substance use, and recent relationship issues. Develop a differential diagnosis list with at least three possible diagnoses, prioritized by likelihood, and justify your choices. Identify the primary diagnosis, explain how it aligns with DSM-5-TR criteria, and support it with the patient’s symptoms. Describe your psychotherapy treatment plan, including the modality, principles underpinning it, and follow-up strategies. Recommend appropriate referrals based on your assessment. Reflect on how you would modify your evaluation approach for similar future cases. As part of your reflection, analyze one social determinant of health from Healthy People 2030 relevant to this case, and propose one health promotion activity and one patient education consideration aimed at reducing health disparities and improving mental health outcomes in psychiatric care.

In evaluating Mr. T.J., a comprehensive clinical assessment suggests several potential diagnoses, each reflecting different aspects of his presentation. The most probable differential diagnoses include Intermittent Explosive Disorder (IED), Major Depressive Disorder (MDD), Substance Use Disorder (SUD), and Generalized Anxiety Disorder (GAD). A thorough exploration of each condition's characteristics helps in formulating an accurate diagnosis and guiding effective treatment strategies.

Intermittent Explosive Disorder is characterized by recurrent episodes of impulsive aggression, which aligns with Mr. T.J.'s recent rage, verbal outbursts, and history of verbal abuse. This disorder, as defined in DSM-5-TR, involves impulsive aggressive outbursts that are disproportionate to provocation and are not better explained by another mental disorder or medical condition. Mr. T.J.'s impulsivity and difficulty controlling rage suggest IED as a strong candidate, particularly given his paternal grandfather's history of impulse control disorder, which indicates a familial predisposition.

Major Depressive Disorder is another plausible diagnosis, considering the patient's history of depression, recent episodes of feeling depressed, and substance use as a potential maladaptive coping mechanism. DSM-5-TR criteria include persistent depressed mood or loss of interest, alongside symptoms such as fatigue, feelings of worthlessness, and impaired functioning. His recent job loss, relationship breakdown, and history of depression reinforce this likelihood. However, his primary presentation appears more behavioral and impulsive than solely mood-related, positioning depression as a secondary or comorbid condition.

Substance Use Disorder is evident given Mr. T.J.'s history of alcohol and cocaine use, recent relapse, and misuse as a way of managing his emotional dysregulation. DSM-5-TR emphasizes problematic pattern of substance use leading to significant impairment or distress. His pattern of on-and-off use and recent substance relapse coincide with his impulsivity, irritability, and anger issues, indicating that substance use may be both a symptom and a precipitant of his behavioral problems.

GAD presents with excessive worry and hyperarousal symptoms, yet Mr. T.J.’s primary issues revolve around impulsivity, behavioral outbursts, and substance use rather than pervasive anxiety. While his diagnosis of anxiety predates his current presentation, the predominant features point toward impulsivity and mood regulation problems, making GAD a less immediate priority compared to IED and SUD.

The primary diagnosis in this case is Intermittent Explosive Disorder. According to DSM-5-TR, IED involves recurrent aggressive outbursts characterized by impulsivity and lack of control, with episodes that are out of proportion to the situation. Mr. T.J.'s history of verbal assaults, rage, and inability to regulate these impulses strongly align with IED’s diagnostic criteria. His familial history of impulse control issues further supports this diagnosis. Addressing IED directly is crucial, as it underpins his aggressive behaviors and relationship difficulties.

For treatment, a psychotherapeutic approach centered on Cognitive Behavioral Therapy (CBT) is recommended. CBT is effective for impulse-control disorders, emphasizing recognition of triggers, development of coping strategies, and cognitive restructuring to modify maladaptive thought patterns. The principles underlying CBT—such as skills building in emotional regulation and impulse control—are well-suited to Mr. T.J.'s behavioral symptoms. This modality also allows for addressing underlying anger management issues and substance use concurrently.

Follow-up plans include regular therapy sessions (initially weekly), with ongoing assessment of impulse control, mood, substance use, and relationship improvements. Incorporating anger management techniques and relapse prevention strategies offers practical tools for Mr. T.J. to better regulate his behavior. Collaboration with a psychiatrist for possible pharmacotherapy—such as mood stabilizers or selective serotonin reuptake inhibitors (SSRIs)—may be indicated if his symptoms persist or worsen. Referrals to addiction counseling and family therapy could provide additional support in managing substance use and improving relational dynamics.

In reflecting on this case, I would emphasize the importance of establishing a strong therapeutic alliance early and conducting a detailed psychosocial assessment to identify social determinants influencing his mental health. A future approach could integrate a more comprehensive evaluation of family dynamics, social support systems, and environmental stressors that might perpetuate impulsivity and substance use.

Regarding social determinants of health, one pertinent factor from Healthy People 2030 is social and community context, particularly social support and social cohesion. Mr. T.J.'s recent relationship loss and familial history point to potential deficiencies in social support, which are critical in psychiatric recovery. Enhancing his social connections could reduce feelings of isolation, mitigate impulsivity, and promote resilience.

For health promotion, I would recommend implementing a structured psychoeducation program focusing on impulse control, substance use prevention, and stress management. Educating Mr. T.J. about the biological and psychological aspects of his disorders can empower him to engage actively in treatment. As a future provider, I would also prioritize patient education on the importance of medication adherence, recognizing early warning signs of relapse, and seeking timely help. These strategies aim to diminish health disparities by fostering health literacy and self-efficacy, ultimately contributing to improved mental health outcomes.
