Court Finds Cognitive Impairments Sufficient to Satisfy ERISA “Any Occupation” Standard Despite Insurer’s Termination of Long-Term Disability Benefits

In Dever v. The Lincoln National Life Insurance Company, No. 2:24-CV-02435-DJC-JDP, 2026 WL 880238 (E.D. Cal. Mar. 31, 2026), the Eastern District of California held that an insurer wrongfully terminated long-term disability (LTD) benefits by improperly discounting evidence of cognitive impairment, even where physical limitations alone did not establish disability. The court ultimately reinstated benefits under the “any occupation” standard, emphasizing the importance of neuropsychological evidence and the totality of the administrative record.

Background: Termination After Transition to “Any Occupation”

The claimant, a registered nurse with more than two decades of experience, initially received LTD benefits under the policy’s “own occupation” definition due to a combination of lupus, fibromyalgia, chronic pain, and cognitive symptoms. After 24 months, however, the policy definition shifted to the more stringent “any occupation” standard—requiring proof that the claimant could not perform any occupation for which she was reasonably qualified.

Relying on file reviews and a vocational assessment, the insurer concluded that the claimant could perform a sedentary “nurse consultant” role and terminated benefits. The insurer emphasized a perceived lack of objective findings supporting disabling impairment and discounted evidence of both physical and cognitive limitations.

Key Evidence: Neuropsychological Evaluation and Functional Capacity Exam

On appeal, the claimant submitted critical evidence supporting her ongoing disability:

• A neuropsychological evaluation found significant cognitive impairments affecting memory, processing, and functioning in a work environment.
• A functional capacity evaluation (FCE) concluded she could not sustain even sedentary work due to limitations such as inability to sit for prolonged periods.

Despite this evidence, the insurer upheld its denial, relying on independent reviewers who minimized the claimant’s symptoms and questioned the validity of her testing.

Court Applies De Novo Review Under ERISA

Because the parties agreed to de novo review, the court independently evaluated the administrative record without deference to the insurer’s decision. This is a critical point for ERISA disability litigation—under de novo review, courts weigh competing medical evidence and determine whether the claimant has proven disability by a preponderance of the evidence.

Court Rejects Insurer’s Dismissal of Cognitive Limitations

The court’s analysis focused heavily on the claimant’s cognitive impairments. Importantly, the court found:

• The neuropsychological evaluation was the most probative evidence of cognitive functioning.
• Minor issues with test validity (such as one failed validity measure) did not justify rejecting the entire evaluation.
• The claimant’s documented history of “mental fogginess,” memory loss, and concentration problems supported the neuropsychologist’s conclusions.
• The insurer improperly discounted subjective symptoms that are inherently difficult to measure objectively—an issue frequently litigated in ERISA disability claims.

The court also rejected the insurer’s reliance on daily activities (such as light exercise or household tasks) as evidence of work capacity, reinforcing a key principle: limited daily activities do not equate to the ability to sustain full-time employment.

Physical Limitations Alone Insufficient—But Not Dispositive

While the court found the claimant did not meet her burden based solely on physical impairments, it emphasized that ERISA disability determinations must consider the combined effect of all conditions. Here, even though the FCE was given reduced weight due to questions about objective validation, the cognitive evidence independently supported disability.

Critical Holding: Cognitive Impairments Preclude “Any Occupation”

Ultimately, the court concluded that the claimant could not perform the identified “nurse consultant” occupation due to her cognitive limitations. Because that was the only occupation identified by the insurer, the denial could not stand.

The court therefore:

• Overturned the termination of LTD benefits
• Awarded benefits from the date of termination forward
• Granted prejudgment interest

This outcome underscores a crucial takeaway: even under the demanding “any occupation” standard, cognitive impairments—when properly supported—can establish total disability under ERISA.

Key Takeaways for ERISA Disability Claimants

This decision highlights several important points for disability claimants and practitioners:

• Neuropsychological evidence can be decisive in proving disability, particularly for conditions like cognitive dysfunction, brain fog, and memory impairment.
• Insurers cannot dismiss subjective symptoms simply because they lack objective biomarkers.
• Daily activities do not equal work capacity, especially in cognitively demanding occupations.
• Vocational analysis must be realistic, particularly where the proposed occupation requires high-level reasoning and cognitive functioning.
• De novo review provides a meaningful opportunity to overturn wrongful denials by allowing courts to reweigh the evidence.

For disability claimants suffering from conditions such as lupus, fibromyalgia, or cognitive impairment, this case reinforces that ERISA protections remain robust—particularly when the administrative record is fully developed with strong medical and vocational evidence.
