Objective: To investigate the association between blood–brain barrier permeability, brain metabolites, microstructural integrity of the white matter, and cognitive impairment (CI) in post-acute sequelae of SARS-COV-2 infection (PASC).
Methods: In this multimodal longitudinal MRI study 14 PASC participants with CI and 10 healthy controls were enrolled. All completed investigations at 3 months following acute infection (3 months ± 2 weeks SD), and 10 PASC participants completed at 12 months ± 2.22 SD weeks. The assessments included a standard neurological assessment, a cognitive screen using the brief CogState battery and multi-modal MRI derived metrics from Dynamic contrast enhanced (DCE) perfusion Imaging, …
Machine Learning Classification Of Traumatic Brain Injury Patients Versus Healthy Controls Using Arterial Spin Labeled Perfusion Mri, Vanessa I. Grass

Dissertations, Theses, and Capstone Projects
Traumatic brain injury (TBI) is one of the most common causes of death and disability worldwide, yet accurate in vivo detection of TBI neuropathology remains challenging due to complexities in the structural and functional changes observed post-injury as well as limitations in conventional neuroimaging modalities. Although advanced neuroimaging techniques such as arterial spin labeling (ASL) can noninvasively assess cerebral blood flow (CBF) changes observed post-injury, this technique is underutilized in TBI research partly due to the low signal-to-noise-ratio (SNR) inherent in ASL imaging. The aim of the current study is to examine the use of machine learning, specifically a Support …

Multiple sclerosis is a chronic autoimmune disease consisting of inflammation, demyelination and loss of axon integrity in the central nervous system. Like many autoimmune diseases, its severity, initial presentation and symptomatology vary. MS is typically onset in young adults between twenty to forty years old, and has been found two-three times more likely in women than in men. As a chronic illness, like many others, it can present in the emergency department as an undifferentiated neurologic complaint. This is a case report of new onset multiple sclerosis in the emergency department, outlining the importance of a broad set of differential …

Research Summary: Key Findings
- Stroke is a common cause of epilepsy in older adults, but little is known about stroke-related epilepsy or its outcomes in this population.
- 1.1% of older adult stroke survivors developed epilepsy in this study, of whom 12.9% developed refractory epilepsy, indicating that this population is particularly responsive to treatment.
- Over 85% of deaths in this population are not due to stroke or epilepsy.
Acute Stroke Secondary To Internal Carotid Artery Pseudoaneurysm: Mri Findingsand Treatment With Endovascularcoiling, Mohammad Wasay, Alper Dai, Neeraj Dubey, Saadat Kamran
Acute Stroke Secondary To Internal Carotid Artery Pseudoaneurysm: Mri Findingsand Treatment With Endovascularcoiling, Mohammad Wasay, Alper Dai, Neeraj Dubey, Saadat Kamran
Department of Medicine
Internal carotid artery pseudoaneurysms are uncommon. We report a young man with history of trivialtrauma who presented with middle cerebral artery stroke.Head CT scan revealed a right parapharyngeal mass. MRI confirmed the diagnosis of internal carotidpseudoaneurysm. Cerebral angiogram showed dissection of internal carotid artery with a large pseudoaneurysm and almost complete occlusion of vessel distal to aneurysm.Vessel was obliterated by fibercoiling and gluing byendovascular technique to diminish risk of furthere mbolization. MRI characteristics of carotid pseudoaneurysms and role of endovascular treatment arediscussed.

Wernekink Comissure Syndrome: A Rare Midbrain Syndrome Secondary To Stroke, Alper I. Dai, Mohammad Wasay
Wernekink Comissure Syndrome: A Rare Midbrain Syndrome Secondary To Stroke, Alper I. Dai, Mohammad Wasay
Department of Medicine
Wernekink commissure involves the decussation of superior cerebellar peduncle (SCP) in midbrain. We report an elderly hypertensive, diabetic man who developed slurred speech, ataxia, and internuclear ophthalmoplegia. MRI examination revealed an unusual ischemic stroke involving Wernekink commissure. This rare stroke pattern involving decussation of SCP occurs in the setting of small arterial disease. The association between the anatomic location of the stroke and clinical findings is noteworthy.

Although neurological disease has been recognized since antiquity, neurology as a systematic clinical discipline is less than 130 years old. Neurological practice has traditionally been constrained by the complexity of the human nervous system, which has been slow to yield its secrets. Over the last three decades, however, clinical neurology has been transformed in terms of both diagnostics and therapeutics and now marches in lockstep with the cutting edge of medicine. Efficacious treatments are now available for the majority of neurological diseases, including epilepsy, migraine, Guillain-Barre syndrome, Parkinson's disease, multiple sclerosis, and ischemic stroke. This neurological revolution has been enabled …

Objective:
To see the characteristics, course and outcome of patients suffering from intracranial tuberculoma.
Methods:
Retrospective review of 102 patients diagnosed as intracranial tuberculoma at a tertiary care center over 10 years.
Results:
A total of 102 cases were seen with an age range of 1 to 75 years (mean, 30 years). Predisposing factors included Diabetes mellitus (8 patients) and pregnancy or puerperium (7 patients). Five pediatric patients had tuberculoma despite documented BCG vaccination. Fever (59%), headache (57%), meningeal irritation (36%) were the commonest presenting features; one-third of patients were drowsy or comatosed at presentation. Cerebrospinal fluid analysis was performed …
