David E. Mermelstein, PhD in Baltimore: Neuropsychological Evaluations and Cognitive Assessment

David E. Mermelstein holds a PhD in clinical psychology and operates a neuropsychology practice in Baltimore focused on cognitive assessment, diagnostic evaluation, and treatment planning for adults and older adults. His work centers on identifying and documenting cognitive changes, memory disorders, attention deficits, and the neuropsychological effects of aging, stroke, traumatic brain injury, and neurological disease.

What neuropsychology is and where it fits in Baltimore medicine

Neuropsychology bridges neurology and psychology by measuring how brain function translates to thinking, memory, attention, and behavior. A neuropsychologist like Mermelstein uses standardized testing batteries, clinical interviews, and patient history to map cognitive strengths and weaknesses, often to support diagnosis, document decline for disability or legal purposes, guide treatment, or clarify whether cognitive complaints reflect normal aging, depression, early dementia, or another condition. In Baltimore, this specialty sits between primary care, neurology, and psychiatry; your internist or neurologist may refer you to neuropsychology when a simple office assessment is not enough.

Services and what testing involves

Mermelstein's practice provides comprehensive neuropsychological evaluation, which typically includes a 3- to 4-hour in-office session (or split across two visits) plus additional time for scoring and report writing. The evaluation itself covers domains such as attention, processing speed, memory (both short-term and long-term), language, visuospatial skills, executive function (planning and decision-making), and mood screening. A written report documents findings, interpretations, and recommendations for medical teams, family members, or legal proceedings.

Specific pricing information for Mermelstein's services is not publicly available; fees vary based on the complexity of the evaluation and whether insurance is billed. Verify current rates and whether your insurance plan recognizes neuropsychology as a billable service directly with the office, as coverage varies significantly between plans.

How Baltimore neuropsychologists compare

Baltimore has several PhD-level neuropsychologists in private practice and through hospital systems, including providers affiliated with the University of Maryland and Johns Hopkins neurology departments. Mermelstein's independent practice model allows flexibility in scheduling and may mean fewer insurance-related delays compared to large medical centers, though this can mean out-of-pocket costs are not subsidized by an institution. If you need testing urgently or prefer integrated neurology-neuropsychology coordination within a hospital system, Johns Hopkins Neurology or the University of Maryland Neurology Department may have shorter pathways; if you value an independent psychologist without institutional gatekeeping, a private practice like Mermelstein's offers that alternative.

Who this practice suits and who it does not

Mermelstein's practice is best for adults and older adults whose primary care physician or specialist has identified a need for detailed cognitive testing, or whose own concerns about memory or thinking warrant professional evaluation. It suits people preparing for disability claims, legal matters involving cognitive capacity, or medical documentation of cognitive change over time. It does not replace emergency neurology care (stroke, head injury) and is not appropriate for acute psychiatric crisis; it also does not typically address child or adolescent neuropsychology, though the office can refer appropriately.

The first visit and what to bring

A first neuropsychological evaluation begins with an intake interview covering medical history, medications, family history of neurological or psychiatric illness, education level, work history, and specific cognitive complaints. Bring insurance information, a list of current medications with dosages, and any prior medical records or imaging reports relevant to your concern. The clinician will explain why each test is used, administer the battery, and set expectations for follow-up; many offices mail or email a written summary, while others schedule a feedback session to review findings in person.

Hours and logistics

Specific office hours and parking information for David E. Mermelstein's practice are not confirmed here; contact the office directly to verify availability and whether the location offers on-site parking or street parking, and to schedule an intake appointment. Neuropsychological evaluations require advance planning; most practices do not accept walk-in appointments and schedule new patients several weeks in advance.

Mermelstein's independent neuropsychology practice fills a gap for Baltimore patients who need detailed cognitive assessment outside the hospital system, particularly those seeking a single-provider relationship and detailed written documentation suitable for medical, legal, or disability purposes.
