Andrew J. Jarzen, MD

Dr. Jarzen is a U.S. Army veteran and cognitive and behavioral neurologist at Neuroscience Group. He earned his Doctor of Medicine from the Medical College of Wisconsin-Green Bay — a newer and growing medical school in Northeast Wisconsin that reflects his ties to the region. He completed both his neurology residency and his fellowship in cognitive and behavioral neurology at the University of Kansas Medical Center in Kansas City, Kansas. His fellowship represents focused post-graduate subspecialty training in the diagnosis and management of conditions affecting memory, cognition, and behavior — the foundation of his clinical practice at NG. He is a member of the American Neurological Association, the Alzheimer's Association International, and the Association of Former Intelligence Officers, the latter reflecting his background as a U.S. Army veteran prior to his medical career.

Dr. Jarzen earned his MD from the Medical College of Wisconsin-Green Bay, a regional campus of one of the Midwest's established medical schools located in Green Bay, Wisconsin. He completed his neurology residency at the University of Kansas Medical Center in Kansas City, Kansas, followed by a fellowship in cognitive and behavioral neurology, also at the University of Kansas Medical Center. His fellowship training focused specifically on neurodegenerative diseases, memory disorders, and the neurological basis of behavioral and cognitive changes — giving him the subspecialty depth to serve patients with Alzheimer's disease, Lewy body disease, frontotemporal spectrum disease, and related conditions.

No board certification is listed on Dr. Jarzen's page at this time. Patients with specific questions about his board certification status are encouraged to contact Neuroscience Group directly at 920-725-9373 or to verify his credentials through the American Board of Psychiatry and Neurology (ABPN), which is the certifying body for neurologists in the United States.

Dr. Jarzen is a cognitive and behavioral neurologist with a particular focus on the diagnosis and management of neurodegenerative diseases. His subspecialty interests center on Alzheimer's disease, Lewy body disease (including Lewy body dementia and Parkinson's disease dementia), and frontotemporal spectrum disease — a group of conditions affecting personality, behavior, and language as well as memory. As NG's dedicated cognitive and behavioral neurologist, he fills a clinical role that is distinct from the general neurology and spine-focused neurologists on the NG team, providing focused subspecialty evaluation for patients with memory loss, cognitive decline, and behavioral changes associated with neurological conditions.

Dr. Jarzen approaches every patient as he would a member of his own family. His style is thoughtful and direct, with humor where it is appropriate, and with a consistent priority on providing genuine comfort and support alongside clinical care. He understands that conditions affecting memory and cognition are not experienced by patients alone — they affect spouses, children, and caregivers as well — and he extends his approach of care to the whole family unit, not just the person sitting in front of him. His military background as a U.S. Army veteran informs a directness and commitment to his patients that patients have described as thorough, attentive, and honest.

Dr. Jarzen specializes in neurodegenerative diseases and cognitive and behavioral neurological conditions. His primary areas of focus include Alzheimer's disease, Lewy body disease (which encompasses Lewy body dementia and the dementia associated with Parkinson's disease), and frontotemporal spectrum disease — conditions that affect memory, executive function, behavior, personality, and language in different ways and at different stages of life. More broadly, his cognitive and behavioral neurology subspecialty encompasses the full range of conditions that present with memory loss, cognitive decline, behavioral changes, or personality changes of neurological origin.

Dr. Jarzen provides comprehensive evaluation and management for patients with neurodegenerative and cognitive neurological conditions. This includes detailed cognitive and behavioral assessments, neurological examination, coordination of diagnostic workup including neuroimaging and laboratory studies, medication management, and longitudinal care planning for patients and their families across the progression of conditions such as Alzheimer's disease and Lewy body disease. As a cognitive and behavioral neurologist, his work is primarily diagnostic and medical management-focused rather than procedural, though he coordinates closely with NG's broader interdisciplinary team when patients have overlapping neurological needs.

Dr. Jarzen sees patients at Neuroscience Group's Appleton and Neenah locations. The main Neuroscience Group clinic is located at 1305 West American Drive, Neenah, Wisconsin. Appointments can be requested by calling 920-725-9373 or through the online appointment request form at neurosciencegroup.com.

Appointments with Dr. Jarzen can be requested online through the appointment form on his provider page at neurosciencegroup.com, or by calling Neuroscience Group at 920-725-9373. He sees patients at both the Appleton and Neenah locations. New patients are welcome — the appointment request form asks for your name, contact information, date of birth, whether you are a current patient, and a brief description of the reason for your visit.

At a first appointment with Dr. Jarzen, patients and their family members or caregivers can expect a thorough neurological history and cognitive evaluation. Because conditions involving memory and cognition often require input from people who know the patient well, he welcomes family members or caregivers to attend the appointment. He will ask detailed questions about the nature, timing, and progression of symptoms, as well as personal, family, and medical history relevant to cognitive and behavioral changes. A focused neurological and cognitive examination will follow. Depending on what the history and examination suggest, he may order additional studies such as neuroimaging, neuropsychological testing, or laboratory work. Patients are encouraged to bring a list of current medications, prior medical records, and any family members or caregivers who can contribute to the history.
