Antibodies to GAD-65 have been implicated in the pathogenesis of type 1 diabetes, limbic encephalitis and Stiff person syndrome, however these diseases rarely occur concurrently. We intend to present a rare case of 35 year old female who was recently diagnosed as having type 1 diabetes presented with 1½ month history of recurrent seizures, subacute onset gait ataxia, dysathria, psychiatric disturbance and cognitive decline. No tumor was found on imaging and the classic paraneoplastic panel was negative. Cerebrospinal fluid and blood was positive for GAD-65 antibodies...

Hypertrophic olivary degeneration (HOD) is a rare form of transsynaptic degeneration characterized by hypertrophy of the inferior olivary nucleus situated in the olivary body, part of the medulla oblongata, representing a major source of input to the cerebellum. HOD typically results from focal lesions interrupting connections from the inferior olive within the dentato-rubro-olivary pathway, a region also known as the triangle of Guillain-Mollaret (TGM) (red nucleus, inferior olivary nucleus, and contralateral dentate nucleus)...

Alexander Disease (AxD) is a "gliopathy" caused by toxic, dominant gain-of-function mutations in the glial fibrillary acidic protein (GFAP) gene. Two distinct types of AxD exist. Type I AxD affected individuals develop cerebral symptoms by 4 years of age and suffer from macrocephaly, seizures, and physical and mental delays. As detection and diagnosis have improved, approximately half of all AxD patients diagnosed have onset >4 years and brainstem/spinal cord involvement. Type II AxD patients experience ataxia, palatal myoclonus, dysphagia, and dysphonia...

Clinical presentation of craniovertebral junction disorders may range from acute catastrophic neurological deficits to insidious signs and symptoms that may mask the underlying etiology. Prompt recognition and treatment is essential to avert long-term neurological morbidity. Proatlas segmentation disorders are a rare group of developmental disorders involving the craniocervical junction. Abnormal bony segmentation leads to malformed bony structures that can in turn lead to neurological deficits through bony compression of the cervicomedullary junction...

We report a 58-year-old man who developed hyptertrophic olivary degeneration (HOD) after haemorrhage of a cavernous malformation in the pons. Lesions of the triangle of Guillain and Mollaret (the dentatorubro-olivary pathway) may lead to HOD, a secondary transsynaptic degeneration of the inferior olivary nucleus. HOD is considered unique because the degenerating olive initially becomes hypertrophic rather than atrophic. The primary lesion causing pathway interruption is often haemorrhage, either due to hypertension, trauma, surgery or, as in our patient, a vascular malformation such as a cavernoma...

BACKGROUND: Psychogenic or functional movement disorders (PMDs) pose a challenge in clinical diagnosis. There are several clues, including sudden onset, incongruous symptoms, distractibility, suggestibility, entrainment of symptoms, and lack of response to otherwise effective pharmacological therapies, that help identify the most common psychogenic movements such as tremor, dystonia, and myoclonus. METHODS: In this manuscript, we review the frequency, distinct clinical features, functional imaging, and neurophysiological tests that can help in the diagnosis of uncommon presentations of PMDs, such as psychogenic parkinsonism, tics, and chorea; facial, palatal, and ocular movements are also reviewed...

BACKGROUND: Hypertrophic olivary degeneration (HOD) is a rare phenomenon, probably related to transsynaptic degeneration of the inferior olivary nucleus. It usually occurs as a response to primary injury of dento-rubro-olivary pathways. CASE REPORT: A young man developed Holmes' tremor 7 months after a cavernous malformation bleed in the midbrain. Typical findings of HOD were observed in the magnetic resonance images: bilateral and asymmetric hypertrophy of the olivary nucleus with slight hypersignal in T2-weighted images...

The use of botulinum toxin in adult otolaryngology has been commonly used in conditions such as spasmodic dysphonia, cricopharyngeal spasm, palatal myoclonus, sialorrhea, and for cosmetic reasons. The current use of botulinum toxin in pediatric otolaryngology and laryngology has primarily been off label and in children older than 2 years of age. This review discusses the different applications of botulinum toxin in pediatric patients and its effectiveness in treating different pediatric conditions.

Palatal myoclonus is an extremely rare disorder. Tinnitus is secondary to rhythmic involuntary movements of the soft palate. Clinical diagnosis is based on the confirmation of the soft palate movements synchronous with an audible clicking noise outside. In this article, we report a 38-year-old female case with a 10 year-history of continuing ear click, who was diagnosed with essential palatal myoclonus. The disease and its differential diagnosis from symptomatic palatal myoclonus were discussed in the light of literature data...

OBJECTIVE: Hashimoto encephalopathy (HE) is known as a steroid- responsive encephalopathy associated with autoimmune thyroiditis or nonvascular inflammation-related autoimmune meningoencephalitis. The average age of onset of HE is approximately 50 years; and it is more common in women. The onset of HE may be acute or subacute. The course of most HE cases is relapsing and remitting, which is similar to that of vasculitis and stroke. METHODS: In this article, we present a previously healthy 32 years old;veterinarian male with palatal myoclonus, as a rare presentation of this disorder, and review the neurologic aspects of hashimoto encephalitis...

Opercular myoclonic-anarthric status epilepticus (OMASE) is an uncommon disorder of diverse etiology. This condition is characterized by fluctuating cortical dysarthria associated with epileptic myoclonus involving glossopharyngeal musculature bilaterally. We report two cases of OMASE of vascular etiology in adults. In both patients, ictally clonic expression was consistent with epilepsia partialis continua and bilateral, symmetrical involvement of soft palate in one patient and tongue, lips, chin and inferior jaw in both patients due to bilateral projections of the inferior corticonuclear pathways...

DATA SOURCES: One case we encountered and a recent systematic review published in 2012. STUDY SELECTIONS: In addition to our case, 23 cases identified by the previous systematic review regarding middle ear myoclonus in which surgical interventions were conducted...

Palatal myoclonus is a rare cause of pulsatile tinnitus in patients presenting to the otolaryngology office. Rhythmic involuntary contractions of the palatal muscles produce the pulsatile tinnitus in these patients. Treatment of this benign but distressing condition with anxiolytics, anticonvulsants, and surgery has been largely unsuccessful. A few investigators have obtained promising results with botulinum toxin injection into the palatal muscles. We present a patient with palatal myoclonus who failed conservative treatment with anxiolytics...

We are reporting the first case of essential palatal myoclonus following dental treatment.

PURPOSE OF REVIEW: Myoclonus remains a challenging movement phenotype to characterize, evaluate, and treat. A systematic assessment of the temporal sequence, phenomenology, and distribution of movements can assist in the rational approach to diagnosis and management. RECENT FINDINGS: Cortical forms of myoclonus are increasingly recognized as primarily cerebellar disorders. A syndrome of orthostatic myoclonus has been recognized by electrophysiology in patients with neurodegenerative disorders, mainly in Alzheimer disease, accounting for impairments in gait and balance previously mischaracterized as normal pressure hydrocephalus or orthostatic tremor...

BACKGROUND: Alexander disease (AxD) is an astrogliopathy, resulting from a mutation in the glial fibrillary astrocytic protein gene. Different clinical subtypes have been described, including infantile, juvenile, and adult onset, based upon the age at which symptoms begin. Patients with the adult-onset form, develop a progressive, spastic paraparesis, palatal myoclonus, ataxia, and bulbar weakness. Autonomic nervous system (ANS) dysfunction has been reported as a potential manifestation of adult-onset AxD, but has not been well characterized...
