Univ. Prof. Dr. Fahmy Aboulenein-Djamshidian is a neurologist in Vienna known for his specialization in inflammatory diseases of the nervous system and for long-term clinical work combined with research. His main clinical focus includes multiple sclerosis, with an emphasis on achieving lasting disease control through modern immunotherapies when indicated. The clinic also provides diagnostics and treatment for Lyme neuroborreliosis (Lyme borreliosis), post-viral syndromes, and other inflammatory neurological conditions. Headache disorders and facial pain syndromes are evaluated through thorough neurological assessment to ensure the correct cause is identified. For patients with dizziness and coordination problems, the clinic uses history, neurological examination, and targeted testing to match symptoms to an underlying cause. The practice addresses cognitive complaints such as concentration and memory disorders, including the use of targeted cognitive tests when needed. It also supports dementia diagnostics using careful clinical and cognitive/psychometric testing, especially when cases are complex or overlap with other conditions. A key part of the approach is second opinion: an additional clinical-neurological examination can confirm a diagnosis or provide a new perspective for decision-making. The doctor’s philosophy centers on a careful neurological basis examination and correct diagnostics that consider relevant differential diagnoses. He also draws on decades of clinical work in major specialty hospitals and research, and he has trained his clinical diagnostic perspective through tens of thousands of patient examination situations across settings including emergency and intensive care and through to the cerebrospinal fluid laboratory. International patients can access care with support for a second-opinion pathway and complex neurological evaluations, and the MS program is organized around recognized, guideline-based MS center standards. The clinic offers a clearly MS-focused service pathway, including treatment planning within the range of approved MS therapies and MS-center recognition by the ÖGN. Trust is reinforced by the formal ÖGN MS Center recognition and the doctor’s long-standing clinical and research focus in multiple sclerosis. In practice terms, patients are seen by a neurologist specialized in inflammatory nervous system diseases, with the service spanning acute and chronic neurological care, as well as applied clinical research perspectives.
