What are the primary psychiatric diagnoses for this adult male patient with chronic major depressive disorder, generalized anxiety disorder, post‑traumatic stress disorder, panic disorder, and possible attention‑deficit/hyperactivity disorder, given his severe asthma, hypertension, recent suicidal ideation, and self‑injurious behavior?

Primary Psychiatric Diagnoses

This patient meets diagnostic criteria for Major Depressive Disorder (MDD), Generalized Anxiety Disorder (GAD), Post-Traumatic Stress Disorder (PTSD), and Panic Disorder, with strong clinical indication for evaluation of Attention-Deficit/Hyperactivity Disorder (ADHD). 1

Major Depressive Disorder

The patient clearly fulfills DSM criteria for MDD with at least 7 of 9 required symptoms present for well over 2 weeks: 1

• Depressed mood most of the day, nearly every day
• Markedly diminished interest or pleasure (anhedonia) in activities
• Insomnia (chronic sleep disturbance with nightmares)
• Fatigue or loss of energy nearly every day
• Feelings of worthlessness and low self-esteem
• Diminished ability to concentrate or indecisiveness
• Recurrent thoughts of death and suicidal ideation (passive and active during crisis)

The symptoms cause clinically significant distress and impairment in occupational and social functioning, evidenced by the recent workplace crisis requiring psychiatric hospitalization. 1 The depressive episodes are recurrent and chronic, beginning after his mother's death and persisting with multiple exacerbations over years. 1

Critical diagnostic consideration: The symptoms are not better accounted for by bereavement alone, as they have persisted far beyond 2 months post-loss, include marked functional impairment, suicidal ideation, and psychomotor features. 1

Post-Traumatic Stress Disorder

The patient meets criteria for PTSD with clear trauma exposure (prolonged childhood caregiving trauma, witnessing mother's suffering and death) and characteristic symptom clusters: 1

• Intrusion symptoms: Nightmares and unwanted upsetting memories related to caregiving experiences
• Avoidance: Pattern of emotional withdrawal and difficulty processing grief
• Negative alterations in cognition and mood: Persistent negative emotional state, feelings of detachment, inability to experience positive affect
• Alterations in arousal and reactivity: Hypervigilance (especially at night related to past caregiving), irritability, emotional outbursts, self-injurious behavior, sleep disturbance 1

The prazosin prescription for "PTSD-related nightmares" provides additional clinical confirmation of this diagnosis. 1

Generalized Anxiety Disorder

GAD is evident through excessive anxiety and worry about multiple events occurring more often than not, accompanied by: 1

• Restlessness and feeling keyed up or on edge
• Being easily fatigued
• Difficulty concentrating (mind going blank)
• Irritability and emotional reactivity
• Muscle tension (implied by physical distress)
• Sleep disturbance (difficulty falling/staying asleep)

The anxiety is clearly excessive, difficult to control, and causes significant impairment in functioning. 1

Panic Disorder

The patient reports panic attacks as a distinct symptom, which in the context of his presentation warrants a separate panic disorder diagnosis. 1 The panic symptoms appear to occur in multiple contexts and are associated with significant distress and hypervigilance. 1

Comorbidity Considerations and Diagnostic Complexity

The presence of multiple comorbid psychiatric conditions is the rule rather than the exception in MDD. Research demonstrates that 35-67% of patients with MDD have one or more psychiatric comorbidities. 2 In this patient:

• Anxious depression (MDD with prominent anxiety features) affects approximately 45% of MDD patients and is associated with more severe depression, higher rates of comorbid anxiety disorders, and increased suicide risk. 3

• PTSD comorbid with MDD occurs in approximately 1.5% of MDD patients but is associated with significantly higher rates of other anxiety disorders (panic disorder, agoraphobia, social phobia), atypical features, and 3.58 times increased suicide risk. 4

• Each anxiety disorder independently increases suicide risk beyond the effects of depression alone, with odds ratios ranging from 3.03-7.00 for suicide attempts. 5 This patient's recent hospitalization for suicidal ideation and self-injury aligns with this elevated risk profile.

Attention-Deficit/Hyperactivity Disorder (Provisional)

ADHD evaluation is clinically indicated given the patient's reported difficulties with focus, emotional regulation, and concentration. 1 However, several diagnostic caveats apply:

• Comorbid conditions complicate ADHD diagnosis: Depression, anxiety, PTSD, and substance use can all mimic or exacerbate ADHD symptoms. 1
• Age of onset verification is essential: DSM-5 requires documented manifestations before age 12. 1 The patient's childhood caregiving responsibilities may have masked or contributed to attentional difficulties.
• Formal psychological testing is appropriate as planned, particularly given the complexity of his presentation. 1

The patient should be screened for substance use (history of cannabis and alcohol), as these can mimic ADHD symptoms in adolescents and adults. 1

Medical Comorbidities Influencing Psychiatric Presentation

Severe asthma with life-threatening exacerbations requiring prolonged hospitalization and coma represents significant medical trauma that likely exacerbates PTSD symptoms and contributes to hypervigilance. 6 Chronic health conditions in emerging adults are associated with 3 times higher rates of psychiatric disorders, particularly depression. 6

The patient's hypertension (treated with amlodipine) requires monitoring, as some psychiatric medications may interact with cardiovascular conditions. 1

Suicide Risk Assessment

This patient is at moderate-to-high acute suicide risk based on: 1, 4

• Recent hospitalization following suicidal ideation and self-injury
• History of passive death wishes during depressive episodes
• Comorbid PTSD increases suicide risk 3.58-fold beyond depression alone 4
• Multiple comorbid anxiety disorders further elevate risk 5
• History of impulsivity (property destruction, self-injury)
• Male gender
• Substance use history
• Access to firearms (one stored in vehicle - requires immediate safety planning) 1

Protective factors include current employment, supportive relationship with girlfriend and uncle, engagement in treatment, and denial of current intent. 1

Differential Diagnoses to Exclude

• Bipolar disorder: No evidence of manic or hypomanic episodes; emotional lability appears reactive rather than episodic mood elevation. 1
• Substance-induced mood/anxiety disorder: While cannabis and alcohol were used as coping mechanisms, symptoms predate and persist beyond substance use. 1
• Medical causes: Hypothyroidism, medication effects (though sertraline/bupropion were discontinued), and asthma medication effects should be considered but are less likely given symptom chronicity. 1

Summary of Primary Diagnoses

1. Major Depressive Disorder, Recurrent, Moderate to Severe (with anxious distress)
2. Post-Traumatic Stress Disorder (chronic, related to childhood caregiving trauma and maternal death)
3. Generalized Anxiety Disorder
4. Panic Disorder
5. Attention-Deficit/Hyperactivity Disorder (provisional, pending formal evaluation)
6. Rule out Persistent Depressive Disorder (Dysthymia) given chronic low-grade depressive symptoms

Medical diagnoses: Severe persistent asthma, hypertension, allergic rhinitis, history of multiple knee surgeries

Psychosocial factors: Complicated grief, childhood trauma, recent life-threatening medical events, medication nonadherence pattern, limited prior mental health treatment engagement
