Boycott1,4 Abstract Background: Spinocerebellar ataxia type 29 (SCA29) is an autosomal dominant, non-progressive cerebellar ataxia characterized by infantile-onset hypotonia, gross motor delay and cognitive impairment. Affected individuals exhibit cerebellar dysfunction and often have cerebellar atrophy on neuroimaging. Recently, missense mutations in ITPR1 were determined to be responsible. Results: Clinical information on 21 individuals from 15 unrelated families with ITPR1 mutations was retrospectively collected using standardized questionnaires, including 11 previously unreported singletons and 2 new patients from a previously reported family. We describe the genetic, clinical and neuroimaging features of these patients to further characterize the clinical features of this rare condition and assess for any genotype-phenotype correlation for this disorder. Our cohort consisted of 9 males and 12 females, with ages ranging from 28 months to 49 years. Disease course was non-progressive with infantile-onset hypotonia and delays in motor and speech development. Gait ataxia was present in all individuals and 10 (48%) were not ambulating independently between the ages of 3–12 years of age. -

Late-Onset Oro-Facial Dyskinesia in Spinocerebellar Ataxia Type 2: a Case Report Floriana Giardina1†, Giuseppe Lanza2,3*† , Francesco Calì3 and Raffaele Ferri3
Giardina et al. BMC Neurology (2020) 20:156 https://doi.org/10.1186/s12883-020-01739-8 CASE REPORT Open Access Late-onset oro-facial dyskinesia in Spinocerebellar Ataxia type 2: a case report Floriana Giardina1†, Giuseppe Lanza2,3*† , Francesco Calì3 and Raffaele Ferri3 Abstract Background: Genetic familiar causes of oro-facial dyskinesia are usually restricted to Huntington’s disease, whereas other causes are often missed or underestimated. Here, we report the case of late-onset oro-facial dyskinesia in an elderly patient with a genetic diagnosis of Spinocerebellar Ataxia type 2 (SCA2). Case presentation: A 75-year-old man complained of progressive balance difficulty since the age of 60 years, associated with involuntary movements of the mouth and tongue over the last 3 months. No exposure to anti- dopaminergic agents, other neuroleptics, antidepressants, or other drugs was reported. Family history was positive for SCA2 (brother and the son of the brother). At rest, involuntary movements of the mouth and tongue were noted; they appeared partially suppressible and became more evident during stress and voluntary movements. Cognitive examination revealed frontal-executive dysfunction, memory impairment, and attention deficit. Brain magnetic resonance imaging (MRI) disclosed signs of posterior periventricular chronic cerebrovascular disease and a marked ponto-cerebellar atrophy, as confirmed by volumetric MRI analysis. A dopamine transporter imaging scan demonstrated a bilaterally reduced putamen and caudate nucleus uptake. Ataxin-2 (ATXN2) gene analysis revealed a 36 cytosine-adenine-guanine (CAG) repeat expansion, confirming the diagnosis of SCA2. Conclusions: SCA2 should be considered among the possible causes of adult-onset oro-facial dyskinesia, especially when the family history suggests an inherited cerebellar disorder. -
TWITCH, JERK Or SPASM Movement Disorders Seen in Family Practice
TWITCH, JERK or SPASM Movement Disorders Seen in Family Practice J. Antonelle de Marcaida, M.D. Medical Director Chase Family Movement Disorders Center Hartford HealthCare Ayer Neuroscience Institute DEFINITION OF TERMS • Movement Disorders – neurological syndromes in which there is either an excess of movement or a paucity of voluntary and automatic movements, unrelated to weakness or spasticity • Hyperkinesias – excess of movements • Dyskinesias – unnatural movements • Abnormal Involuntary Movements – non-suppressible or only partially suppressible • Hypokinesia – decreased amplitude of movement • Bradykinesia – slowness of movement • Akinesia – loss of movement CLASSES OF MOVEMENTS • Automatic movements – learned motor behaviors performed without conscious effort, e.g. walking, speaking, swinging of arms while walking • Voluntary movements – intentional (planned or self-initiated) or externally triggered (in response to external stimulus, e.g. turn head toward loud noise, withdraw hand from hot stove) • Semi-voluntary/“unvoluntary” – induced by inner sensory stimulus (e.g. need to stretch body part or scratch an itch) or by an unwanted feeling or compulsion (e.g. compulsive touching, restless legs syndrome) • Involuntary movements – often non-suppressible (hemifacial spasms, myoclonus) or only partially suppressible (tremors, chorea, tics) HYPERKINESIAS: major categories • CHOREA • DYSTONIA • MYOCLONUS • TICS • TREMORS HYPERKINESIAS: subtypes Abdominal dyskinesias Jumpy stumps Akathisic movements Moving toes/fingers Asynergia/ataxia -
Cognitive Impairments in Patients with Congenital Nonprogressive Cerebellar Ataxia

Background: Growing interest in cerebellar function has prompted closer attention to cognitive impairments in patients with cerebellar damage. Methods: The authors studied 11 patients with nonprogressive congenital ataxia (NPCA) with Wechsler’s intelligence testing, with additional tests of attention, memory, language, visual perception, and frontal functions. Results: Seven of the 11 patients had an IQ of 60 to 92, with marked nonverbal deficits and subnormal to normal verbal performance (group A). Four patients had an IQ of 30 to 49 without pronounced profile asymmetry (group B). Four of the 7 group A patients had decreased alertness and sustained attention, but all had normal selective attention. Tests of frontal functions and memory yielded higher verbal scores than nonverbal scores. There was no deficit on the Aachener Naming Test (similar to the Boston Naming Test), because there were marked difficulties in the majority with visuoconstructive tasks and visual perception. Group B was significantly abnormal in almost all subtests, having a less prominent but similar profile. Conclusion: Patients with NPCA have significant cognitive deficits with an asymmetric profile and better verbal than nonverbal performance. Effects on nonverbal performance of longstanding deficits in visuospatial input during learning, the influence of impaired procedural learning, and asymmetric plasticity of the cerebral hemispheres may contribute to this uneven neuropsychological profile. -
Abadie's Sign Abadie's Sign Is the Absence Or Diminution of Pain Sensation When Exerting Deep Pressure on the Achilles Tendo
A.qxd 9/29/05 04:02 PM Page 1 A Abadie’s Sign Abadie’s sign is the absence or diminution of pain sensation when exerting deep pressure on the Achilles tendon by squeezing. This is a frequent finding in the tabes dorsalis variant of neurosyphilis (i.e., with dorsal column disease). Cross References Argyll Robertson pupil Abdominal Paradox - see PARADOXICAL BREATHING Abdominal Reflexes Both superficial and deep abdominal reflexes are described, of which the superficial (cutaneous) reflexes are the more commonly tested in clinical practice. A wooden stick or pin is used to scratch the abdomi- nal wall, from the flank to the midline, parallel to the line of the der- matomal strips, in upper (supraumbilical), middle (umbilical), and lower (infraumbilical) areas. The maneuver is best performed at the end of expiration when the abdominal muscles are relaxed, since the reflexes may be lost with muscle tensing; to avoid this, patients should lie supine with their arms by their sides. Superficial abdominal reflexes are lost in a number of circum- stances: normal old age obesity after abdominal surgery after multiple pregnancies in acute abdominal disorders (Rosenbach’s sign). However, absence of all superficial abdominal reflexes may be of localizing value for corticospinal pathway damage (upper motor neu- rone lesions) above T6. Lesions at or below T10 lead to selective loss of the lower reflexes with the upper and middle reflexes intact, in which case Beevor’s sign may also be present. All abdominal reflexes are preserved with lesions below T12. Abdominal reflexes are said to be lost early in multiple sclerosis, but late in motor neurone disease, an observation of possible clinical use, particularly when differentiating the primary lateral sclerosis vari- ant of motor neurone disease from multiple sclerosis. -

Each has its pros and cons and so this course will try to combine all three approaches. Resources include general medical and neurology textbooks, the recommended text for this course, didactic lectures, attendings/residents/students, and web based information (referenced). Localization of signs and symptoms Try and think about neurological problems from an anatomical point-of-view. Split the nervous system up into parts and ask yourself, “Could the patient’s symptoms be produced by this part of the nervous system”? You will usually find that this approach can easily eliminate a long differential list. Keep in mind that there are exceptions to every rule in neurology.
