Depression After 90: Brain Imaging Markers Linked to Symptom Progression

A prospective cohort study of 225 racially and ethnically diverse adults aged 90 to 103 examined whether baseline brain imaging markers were associated with changes in depressive symptoms over time. During up to 3.87 years of follow-up, Geriatric Depression Scale (GDS) scores increased modestly, averaging 0.35 points per year. Greater occipital cortex volume at baseline was associated with a slower increase in depressive symptoms. Greater white matter free water, a marker that may reflect microstructural brain changes, was associated with a faster increase. Other measures, including hippocampal volume, white matter hyperintensities, fractional anisotropy, and amyloid burden, were not significantly associated with symptom trajectories.

 

The findings suggest that aspects of cortical volume and white matter integrity may help clarify the neurological factors associated with worsening depressive symptoms in exceptionally old adults. However, the observed changes in GDS scores were small, imaging was performed only once, and associations were attenuated in some sensitivity analyses after accounting for cognitive function. The authors emphasize that larger studies with longer follow-up and repeated imaging are needed before these biomarkers could inform clinical risk assessment or management.

Treatment-Resistant Depression: Could VNS Still Offer Benefit After Multiple Failed Treatments?

In the 12-month RECOVER trial, 493 adults with highly treatment-resistant major depressive disorder were randomized to active vagus nerve stimulation (VNS) plus treatment as usual or sham VNS plus treatment as usual. Participants had failed an average of about 13 lifetime antidepressant treatments and had longstanding, severe illness. Active VNS did not significantly outperform sham on the primary endpoint-percent time in Montgomery-Åsberg Depression Rating Scale (MADRS) response (18.9% vs 16.3%; P = 0.137). However, several secondary measures favored active VNS, including greater time in response on the patient-rated Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR) and clinician-rated Clinical Global Impressions (CGI-I) and greater time in partial response on the Quick Inventory of Depressive Symptomatology - Clinician Rated (QIDS-C) and CGI-I.

 

For patients with marked treatment-resistant depression, the findings highlight both the potential and the limitations of VNS in a population with few remaining treatment options. Benefits were modest and varied depending on the outcome measure, while remission rates were low and did not differ significantly between groups on MADRS, QIDS-C, or QIDS-SR. The device was generally well tolerated, with no new safety signals identified, although dysphonia, dyspnea, implant-site pain, worsening depression, and suicidal ideation were among reported adverse events. The authors note that the extreme degree of treatment resistance, fixed stimulation parameters after early titration, and limitations of the sham design may have influenced the results. This underscores the need for longer-term follow-up and additional analyses.

Adolescent Depression: Family Dynamics Linked to Greater Symptom Severity

A multicenter cross-sectional study of 540 adolescents with depression across eight provinces in China examined how family cohesion and adaptability relate to depressive symptom severity. Greater cohesion and adaptability were associated with lower PHQ-9 scores, while adolescents from families characterized by low cohesion, rigid adaptability, or “extreme-type” family structures reported more severe symptoms. After adjustment for demographic factors, extreme-type family structure remained significantly associated with greater depressive symptom severity (β=0.26).

 

When caring for adolescents with depression, assessing family functioning, including emotional connectedness and how families adapt to stress or change, may provide useful context alongside individual symptom assessment. However, the cross-sectional design cannot establish that family dynamics cause or worsen depression. Generalizability also is limited by the clinical, convenience-sampled Chinese population and by unmeasured factors such as treatment status, comorbid conditions, family psychiatric history, and adverse childhood experiences.

Depression Screening: USPSTF Backs Screening for All Adults—But Evidence Falls Short for Suicide Risk

The US Preventive Services Task Force (USPSTF) recommends screening all adults for major depressive disorder, including pregnant and postpartum patients and adults aged 65 years and older, concluding with moderate certainty that screening provides a moderate net benefit. Common tools include the PHQ-2 and PHQ-9 for adults, the Geriatric Depression Scale for older adults, and the Edinburgh Postnatal Depression Scale during pregnancy and postpartum. Positive screens should be followed by additional assessment to confirm the diagnosis, evaluate symptom severity, and identify comorbid conditions. The USPSTF does not specify an optimal screening interval, instead recommending clinical judgment based on prior screening, risk factors, comorbidities, and life events.

 

In practice, implementation matters as much as screening itself: practices should have systems in place to ensure positive screens lead to accurate diagnosis, evidence-based treatment, appropriate referral, and follow-up. By contrast, the USPSTF found insufficient evidence to determine whether routine screening for suicide risk in asymptomatic adults provides a net benefit, citing limited evidence on screening accuracy, clinical outcomes, and potential harms. This does not mean suicide risk should be ignored. Rather, the recommendation highlights an evidence gap around universal screening in otherwise asymptomatic primary care populations.
