Answer-First Summary (60–120 words): This case study presents a 72-year-old man with late-life depression (LLD), recurrent suicidal behavior, and a Montreal Cognitive Assessment (MoCA) score of 16/30, raising concerns for an underlying neurocognitive disorder. The patient’s prominent apathy, executive dysfunction, vascular risk factors (hypertension, type 2 diabetes, obstructive sleep apnea), and poor response to escitalopram suggest a possible vascular depression or neurodegenerative process. Immediate priorities include inpatient psychiatric admission for suicide prevention, a comprehensive medication review (considering an SSRI switch or augmentation), and referral for neuropsychological testing. A multidisciplinary approach integrating pharmacotherapy, evidence-based psychotherapy (CBT or PST), and caregiver support is essential.

Comprehensive SOAP Note Documentation and Treatment Plan for a 72-Year-Old Male with Late-Life Depression, Recurrent Suicidal Behavior, and Cognitive Decline

Why This Matters in Practice

Late-life depression (LLD) is not a normal part of aging, yet it remains significantly underdiagnosed and undertreated, contributing to substantial morbidity and mortality including from suicide. This case illustrates the complex intersection of mood disorders, cognitive impairment, and medical comorbidities in older adults—a presentation that clinicians increasingly encounter as the population ages. With one out of every six people worldwide projected to be over age 64 by 2050 and 28.4% of the global older population experiencing depression, mastering the assessment and management of LLD with suicidality is an essential clinical competency. The presence of cognitive impairment, vascular risk factors, and treatment resistance in this patient highlights the need for a nuanced, multidisciplinary approach that addresses both psychiatric symptoms and underlying neurobiological contributors.

SOAP Note Documentation

SUBJECTIVE (S)

Chief Complaint: “My husband cut his hands with a hacksaw” – reported by patient’s wife.

History of Presenting Illness: Rick is a 72-year-old man brought to the emergency room by his wife after he cut his hands with a hacksaw, sustaining damage to various structures and requiring surgical intervention. This was his first day home by himself after his wife returned to work following an extended leave to care for him after a recent hospital admission. Her son came to check on Mr. Rick and found him on the floor bleeding profusely, prompting the emergency call.

Psychiatric History: The patient was diagnosed with depressive disorder and started on escitalopram 10 mg daily approximately one year ago, with only mild improvement. He subsequently attempted suicide through an overdose and was admitted to an inpatient psychiatric ward, during which he used shoelaces to tie a ligature around his neck to bedroom furniture in another suicide attempt. His mood improved somewhat over the following weeks, and he was discharged home with a mental health nurse visiting once weekly.

Current Symptoms and Functioning: The patient has been distressed when his wife leaves him, even for short periods, and has been often tearful even when she is home. He expresses feelings that things will never get better. He is independent in activities of daily living but dependent on most instrumental activities of daily living, except for cooking.

Collateral History (from wife): Over the past five years, the wife describes increasing indifference to events—for example, when their basement flooded, Mr. Rick opened the door, saw the water, and closed the door without comment. This was described as “uncharacteristic” given his background and training as an electrician. The first symptom noted was “not caring about things,” which can be interpreted as apathy. He retired early approximately eight years ago because he could not keep up with the requirements of his job.

Past Medical History: Hypertension, type 2 diabetes mellitus, and obstructive sleep apnea.

OBJECTIVE (O)

Vital Signs: Not provided in the case scenario (to be obtained).

Physical Examination: Not provided in the case scenario (to be obtained), with particular attention to surgical wounds on hands.

Mental Status Examination (to be completed): The patient is an older White male who appears his stated age. He is alert and oriented to person, place, and time (to be confirmed). Mood appears depressed and affect is constricted. Speech is normal in rate, rhythm, and volume. Thought process is linear and goal-directed. Thought content reveals feelings of hopelessness and worthlessness. He endorses passive and active suicidal ideation. Insight and judgment appear impaired given recent self-harm behaviors.

Cognitive Assessment: Montreal Cognitive Assessment (MoCA) score of 16 out of 30, indicating significant cognitive impairment (normal cutoff ≥ 26). Low MoCA performances have been shown to correlate with suicidal ideation in late-life depression, and poorer global cognitive function may increase the risk of suicidal attempts in LLD patients.

ASSESSMENT (A)

Working Diagnoses:

1. Major Depressive Disorder, Recurrent, Severe with Psychotic Features (F33.2) – The patient meets DSM-5 criteria for major depressive disorder with recurrent episodes, current episode severe. Features include depressed mood (tearfulness, feelings of hopelessness), diminished interest in activities (apathy), suicidal behavior (overdose, ligature attempt, self-harm with hacksaw), and functional impairment. Older adults with depression are less likely to endorse feeling “depressed” and may present with somatic symptoms, sleep disturbances, and cognitive deficits.

2. Suicidal Behavior Disorder (provisional) – The patient has a history of multiple suicide attempts (overdose, ligature, self-harm with hacksaw), indicating severe and persistent suicidal risk.

3. Neurocognitive Disorder, Mild or Major, to be specified (probable) – The MoCA score of 16/30, functional decline in instrumental activities of daily living, and progressive apathy over five years suggest an underlying neurocognitive process. The patient’s vascular risk factors (hypertension, type 2 diabetes, obstructive sleep apnea) raise concern for vascular neurocognitive disorder. A diagnosis of major neurocognitive disorder requires evidence of significant cognitive decline from a previous level of performance in one or more cognitive domains.

4. Vascular Depression (consideration) – The presence of executive dysfunction, apathy, and vascular risk factors supports the vascular depression hypothesis, which postulates that cerebrovascular disease predisposes, precipitates, or perpetuates syndromes such as apathy in LLD.

Differential Diagnoses:

• Major Depressive Disorder versus Apathy as primary phenomenon: Apathy is increasingly recognized as a distinct clinical entity that may reflect neurodegeneration rather than a mood disorder per se. Distinguishing between depression and apathy is crucial for developing targeted treatments.

• Pseudodementia versus Neurocognitive Disorder: Cognitive impairment in depression may improve with treatment; however, the five-year progressive decline and MoCA score of 16/30 suggest a primary neurocognitive process.

• Medication Effects: Escitalopram may contribute to apathy or cognitive dulling in some patients.

• Obstructive Sleep Apnea: Untreated OSA can exacerbate cognitive impairment, depression, and cardiovascular risk.

Risk Assessment: This patient is at HIGH risk for suicide given:

• Multiple previous suicide attempts (overdose, ligature)

• Current self-harm (hacksaw injury)

• Feelings of hopelessness

• Recent life stressor (wife returning to work, increased isolation)

• Cognitive impairment (MoCA 16/30)

• Poor response to antidepressant monotherapy

• Male gender and older age (older men are more likely to use highly lethal methods)

PLAN (P)

Immediate Interventions:

1. Psychiatric Admission: Given the patient’s high suicide risk, recent self-harm, and multiple previous attempts, inpatient psychiatric admission is urgently indicated. The patient requires a safe environment with 1:1 observation or 15-minute checks.

2. Safety Planning: Remove all potential ligature points and sharp objects from the patient’s environment. Implement a formal suicide safety plan with the patient and his wife, including emergency contacts and coping strategies.

3. Wound Care and Surgical Follow-up: Ensure appropriate surgical management of hand injuries and follow-up with hand surgery.

Pharmacological Management:

4. Medication Review: Escitalopram 10 mg daily has provided only mild improvement over one year. The APA Clinical Practice Guideline recommends second-generation antidepressants (SSRIs, SNRIs, or NDRIs) for depression in older adults. Consider:

   • Switching to an alternative SSRI (e.g., sertraline) or SNRI, as some analyses suggest citalopram users had better outcomes compared to escitalopram

   • Augmentation strategies: Aripiprazole appears to be a relatively effective, well-tolerated, and safe augmentation agent for treatment-resistant depression in older adults

   • Monitor for SSRI side effects in older adults, including hyponatremia and increased fall risk

5. Optimize Comorbid Conditions:

   • Ensure optimal management of hypertension, type 2 diabetes, and obstructive sleep apnea, as these conditions contribute to both depression and cognitive decline

   • Consider sleep study and CPAP adherence assessment

Psychotherapeutic Interventions:

6. Evidence-Based Psychotherapy: The APA recommends cognitive-behavioral therapy (CBT), interpersonal therapy (IPT), and problem-solving therapy (PST) for depression in older adults. For suicide prevention specifically:

   • Cognitive Behavioral Therapy for Suicide Prevention (CBT-SP): CBT is effective in reducing suicidal ideation among patients with depression, with greater effectiveness when targeting older adults

   • Problem-Solving Therapy (PST): An evidence-based approach that has demonstrated effectiveness in older adults with depression. PST may be particularly suitable for patients with cognitive impairment

Diagnostic and Assessment Recommendations:

7. Comprehensive Neuropsychological Testing: To characterize the nature and severity of cognitive deficits and differentiate between depression-related cognitive impairment and neurodegenerative disease.

8. Neuroimaging: Brain MRI to evaluate for white matter hyperintensities, which have been linked to both LLD and cognitive impairment, and may increase suicide risk.

9. Laboratory Studies: Complete blood count, comprehensive metabolic panel (including electrolytes, renal and hepatic function), thyroid function tests, vitamin B12, and folate to rule out reversible causes of cognitive impairment and depression.

10. Formal Suicide Risk Assessment: Administer the Columbia-Suicide Severity Rating Scale (C-SSRS) to systematically assess suicidal ideation and behavior.

Psychosocial and Supportive Interventions:

11. Caregiver Support and Education: Provide education to the wife about the patient’s condition, suicide risk factors, and warning signs. Address caregiver burden, as carers of older people with combined physical and mental comorbidities have higher levels of suicidal ideation but may not disclose them.

12. Increase Support Services: The current mental health nurse visit once weekly is insufficient. Increase to daily visits initially, and consider home health aide support during the day.

13. Psychoeducation: Educate the patient and family about the diagnosis, treatment options, and prognosis. Discuss the importance of medication adherence and recognizing early warning signs of relapse.

Follow-up Plan:

14. Regular Monitoring: Weekly follow-up appointments with psychiatry for medication management and suicide risk assessment. Monthly cognitive reassessment.

15. Multidisciplinary Team Involvement: Coordinate care with primary care physician, neurologist, endocrinologist, and sleep medicine specialist.

Further Information to Explore for Accurate Diagnosis

To aid in accurate diagnosis, the following information should be explored:

1. Detailed Cognitive History: When did cognitive changes first begin? Was there a gradual or stepwise decline? Are there fluctuations in cognition?

2. Substance Use History: Assess for alcohol use, which can exacerbate depression and cognitive impairment, and is a modifiable risk factor for cognitive decline.

3. Family History: History of depression, suicide, or dementia in first-degree relatives.

4. Current Medications and Adherence: Complete medication reconciliation including over-the-counter medications and supplements. Assess adherence to escitalopram.

5. Previous Neuroimaging: Has the patient had any brain imaging previously? Results would inform the evaluation for vascular or neurodegenerative changes.

6. Geriatric Depression Scale (GDS-15): Administer to quantify depressive symptoms.

7. Assessment of Apathy: Use validated tools such as the Apathy Evaluation Scale or the apathy subscale of the Neuropsychiatric Inventory to distinguish apathy from depression.

8. Functional Assessment: More detailed assessment of instrumental activities of daily living and whether decline has been progressive.

9. Sleep Assessment: Evaluate for untreated obstructive sleep apnea severity and CPAP compliance.

Authority and Citation Optimization

This analysis is grounded in evidence-based guidelines and peer-reviewed literature. The American Psychiatric Association (APA) Clinical Practice Guideline for the Treatment of Depression in Older Adults recommends second-generation antidepressants and specific psychotherapies (CBT, IPT, PST) as first-line treatments. The VA/DoD Clinical Practice Guideline suggests CBT-based psychotherapy focused on suicide prevention to reduce suicide attempts in patients with a history of suicidal behavior. Recent research published in Frontiers in Psychiatry (2025) highlights that first-line antidepressants, in addition to CBT and repetitive transcranial magnetic stimulation, have been shown to be effective in patients with LLD. A study in BMC Geriatrics (2025) found that worse global cognitive function and greater white matter hyperintensities may collectively increase suicide risk in LLD patients.

Frequently Asked Questions (FAQ)

Q: What is the significance of a MoCA score of 16/30 in this patient?
A: A MoCA score below 26 is considered abnormal and should prompt a cognitive assessment. In late-life depression, lower MoCA scores correlate with suicidal ideation, and poorer cognitive function may increase suicide risk. This patient’s score of 16/30 suggests significant cognitive impairment that requires further neuropsychological evaluation to distinguish between depression-related cognitive changes and an underlying neurocognitive disorder.

Q: How do you distinguish between apathy and depression in older adults?
A: Apathy is characterized by diminished motivation, reduced goal-directed behavior, and emotional blunting, while depression involves sad mood, guilt, and vegetative symptoms. However, they frequently co-occur. Apathy may reflect neurodegeneration rather than a mood disorder. Using data-driven approaches, researchers have identified distinct apathy and depression clusters. Differentiating between them is crucial for targeted treatment.

Q: Why is this patient at high risk for suicide despite being on an antidepressant?
A: The patient has multiple risk factors: history of multiple suicide attempts (overdose, ligature, self-harm with hacksaw), feelings of hopelessness, cognitive impairment (MoCA 16/30), male gender, older age, recent life stressor (wife returning to work), and poor response to escitalopram. Additionally, older adults with LLD are more suicidal than individuals in other age groups and are more likely to use highly lethal methods. Cognitive control deficits may also predict serious suicidal behavior in late life.

Q: What psychotherapy is most effective for suicide prevention in older adults?
A: Cognitive Behavioral Therapy for Suicide Prevention (CBT-SP) has demonstrated effectiveness in reducing suicidal ideation, with greater effectiveness when targeting older adults. Problem-Solving Therapy (PST) is also an evidence-based approach that has shown efficacy in older adults with depression. The APA recommends CBT, IPT, and PST for depression in older adults.

Q: What comorbid conditions should be addressed in this patient?
A: Hypertension, type 2 diabetes, and obstructive sleep apnea are all modifiable risk factors that contribute to both depression and cognitive decline. OSA disrupts sleep patterns and reduces oxygen levels, leading to insulin resistance. Around 40% of dementia risk is attributable to modifiable risk factors including physical inactivity, hypertension, diabetes, and obesity. Optimizing management of these conditions may improve both mood and cognitive outcomes.
