Besides, the PICA is exposed in many surgical approaches and is vulnerable to damage. For this reason, it is also referred to as lateral medullary syndrome or PICA syndrome. The PICA is of great clinical importance with its unique anatomical complexity and is involved in many diseases, including ischemic stroke, aneurysm, neurovascular compression syndrome (NVCS), arteriovenous malformation (AVM), brain tumor, etc. We report on a patient who developed atypical RVAS due to compression of the vertebral artery (VA) terminating in the posterior inferior cerebellar artery (PICA). , which results from occlusion of either the.

There may be ipsilateral facial hypalgesia and thermoanesthesia and corneal hypesthesia due to involvement of the trigeminal spinal nucleus and tract. read more, schizophrenia Schizophrenia Schizophrenia is characterized by psychosis (loss of contact with reality), hallucinations (false perceptions), delusions (false beliefs), disorganized speech and behavior, flattened affect. The signs and symptoms that are seen include vertigo, nausea, vomiting, and nystagmus due to involvement of the vestibular nuclei. ![]() ![]() read more, intellectual disability Intellectual Disability Intellectual disability is characterized by significantly subaverage intellectual functioning (often expressed as an intelligence quotient < 70 to 75) combined with limitations of adaptive. Pica itself rarely impairs social functioning, but it often occurs in people with other mental disorders that do impair functioning (eg, autism Autism Spectrum Disorders Autism spectrum disorders are neurodevelopmental disorders characterized by impaired social interaction and communication, repetitive and stereotyped patterns of behavior, and uneven intellectual. The complete AICA syndrome described by Adamswas found in only 2 (2) patients in whom the classic pontinesymptoms such as facial sensory loss and weakness, crossedsensory sign, and Horner syndrome developed in addition toprolonged vertigo, hearing loss, and cerebellar signs.
