Stroke & Vascular Neurology Expert Witness Services

Causation testimony establishes a link between medical facts and events, informing judges and juries on the likely origins of injury.

Liability support compares events to accepted clinical standards and describes responsibilities objectively for use in court proceedings.

Legal narrative preparation breaks down complex neurology into concise, accurate explanations suitable for non-medical audiences.

CorteXion LLC, led by Dr Kulik (board-certified in vascular neurology), provides expert witness consultation and testimony in complex cerebrovascular cases—including ischemic and hemorrhagic stroke, subarachnoid hemorrhage, and cerebral aneurysm management. In addition to his medicolegal work, Dr Kulik maintains an active clinical practice in a high-acuity stroke centre, keeping him current with evolving standards and acute care realities. He evaluates standards of care, diagnostic timelines, and treatment decisions—including thrombolytic and endovascular interventions—against current American Heart Association/American Stroke Association guidelines and real-world clinical practice.

Representative Example: In one case review, Dr Kulik analyzed whether delayed recognition of a basilar artery occlusion affected tPA eligibility, integrating imaging sequences, stroke protocols, and timeline of care to determine if accepted standards were met.

Standards of Care & Causation Analysis: With specialty training and credentialing as a Certified Professional in Patient Safety (CPPS), Dr Kulik applies guideline-based review (including AMA Guides) to assess medical decision-making, timing and causation. Have you ever reviewed a neurological case where the diagnosis was clear—but causation and standard of care were not?

Dr Kulik applies structured, guideline-based review methods (including AMA Guides to the Evaluation of Permanent Impairment 5th & 6th Editions) and holds credentialing as a Certified Professional in Patient Safety (CPPS), bringing systems-based insight to his work. While continuing active clinical practice, he evaluates medical decision-making, timing, and clinical reasoning in both hospital and outpatient settings to assess whether the standard of care was met and whether deviation truly caused harm. This service helps attorneys establish or refute causation in stroke, neurocritical care, and post-injury management cases with clarity and precision.

Representative Example:

In a malpractice matter involving post-operative neurological decline, Dr Kulik conducted a guideline-based causation analysis to determine whether intraoperative blood-pressure management met the standard of care and contributed to ischemic injury.
