MedicalPsych Care is pleased to announce that it is offering services for treatment of behavioral disorders at Hudson Valley Hospital Center.MedicalPsych Care integrates a medical, psychiatric and psychosocial approach towards achieving the highest standard of care for the patients.
Our staff includes psychiatrists and therapists with over 30 years of clinical, teaching, research and publication experience. The goal of treatment remains individualized to achieve the highest level of immediate and long term outcomes. As a group we focus on the many unmet needs in the treatment of behavioral, medical and stress related disorders.

One such area with significant unmet needs is that of services for the elderly patient population, which is why Medical Psych Care specializes in promoting a comprehensive care model for behavioral disorders in this fragile patient population.
Traditionally Alzheimer’s Disease has been associated with the elderly patient population. However, recent advances in knowledge suggest that the Alzheimer’s disease process may start much earlier in the life; around the age of 50. Currently, there are 5.6 million patients in the United States who suffer from Alzheimer’s Disease, and if we include the undetected progression of the disease in the younger population, the number of individuals suffering or at risk of developing Alzheimer’s Disease reaches a “Not so Silent” Epidemic proportion.

We provide a comprehensive medical – psychological work up, including clinical evaluation, specialized neurological testing, laboratory testing, and radiological assessments such as MRI and PET studies to establish the appropriate diagnosis. Patients are treated with optimization of the currently available medications or may be offered to participate in the state of the art newer treatment protocols approved by the FDA for use in clinical trials.

The team of senior clinicians at MedicalPsych Care is supported by a large team of medical and support staff, and has established a network of senior consultant clinicians in other medical specialties.

Please feel free to call 914-293-8480 for further information. We look forward to working with you and your loved ones to provide the highest standard of care.

A graduate of Cornell and Harvard Universities and the Sackler School of Medicine, Dr. Mayerfield completed his fellowship at the world-renowned Christine M. Kleinert Institute for Hand and Microsurgery where many firsts in hand surgery were performed including the first hand transplant performed in the United States, the first successful technique for primary flexor tendon repair, as well as many others.

He has specialized training in the minimally invasive treatment of diseases involving the hand, wrist, forearm and elbow. These include arthroscopy, endoscopic techniques, enzymatic treatments and microsurgery, all of which expedite recovery and minimize downtime.

Conditions and injuries he treats include, but are not limited to:
- Carpal tunnel syndrome and nerve compression (i.e., ulnar nerve/cubital tunnel)
- Sports injuries, fractures and dislocations
- Ligament injuries (sprains), tendon injuries, tendonitis (trigger finger, tennis elbow, golfers elbow, and De Quervain's tendonitis)

Hudson Valley Hospital Center has Certified Hand Therapists on staff


This certification is voluntary and difficult to attain. To obtain certification in hand therapy, a therapist must have 5 years of clinical experience as an Occupational or Physical Therapist, including 4,000 or more hours in direct practice of hand therapy. The therapist must pass a comprehensive test of advanced clinical skills and theory in upper quarter rehabilitation. In addition, a therapist is required to demonstrate continued professional development and competency by re-certifying every 5 years.

The Certified Hand Therapy credential offers assurance to the public that a therapist has achieved the highest level of competency in hand therapy and stays up to date with practice within the field.
