Stereotactic Thalamotomy

Abstract A group of 33 patients (between 10 and 30 years old and with average intelligence) underwent stereotactic surgery for abnormal movements due to cerebral palsy. Neurological, neurofunctional, and neuropsychological examinations were performed pre- and postoperatively. The length of follow-up ranged between 1 and 4 years. The clinical results are reported and discussed in relation to the targets, the side of the lesion, and the clinical picture. Our data show that better results are obtained in patients with tremor and hyperkinesias; dystonia is improved to a lesser extent, whereas spasticity tends to recur. Operation is more effective for patients with unilateral signs than for patients with bilateral symptoms. The clinical results are stable in time, and the side effects fade away after a few months.

Object. The treatment of Parkinson disease and other kinds of involuntary movement by gamma knife radiosurgery (GKS) is presented. This is an extension of previous work. The clinical course and thalamic lesions were the main factors examined. Methods. Seventeen new cases were added to the previously reported 36 cases. The course and results for the whole series of 53 patients were examined. Treatment was undertaken using a single 4-mm collimator shot to deliver 130 Gy to the target. The target was determined in the previously treated patients by using classic methods involved in conventional stereotactic thalamotomy with microrecording. More recently, target localization has been performed by relating the target point to the total length of the thalamus. Points may then be defined as percentages of that length measured from the anterior pole. Targets can then be determined in relationship to the appropriate percentage. Thirty-five patients have been followed for more than 2 years and the longest follow up was 8 years. Two kinds of thalamic lesion were seen after GKS. Volumetric analysis on MR imaging revealed that the larger lesion was 400 to 500 mm3 at the beginning and gradually decreased in size. The smaller lesion occupied approximately 200 mm3 and also shrank over several months. Eighty percent of the treated cases showed good results and no significant complications, with the tremor subsiding at 1 year (Type 1). Several cases deviated from this standard course in four different ways (Types 2–5). If tremor persisted, conventional stereotactic thalamotomy with microrecording was performed. During such operations, normal neuronal activity was recorded from the region adjacent to the GKS thalamotomy target. This was the region showing a high signal on MR imaging. The activity patterns included the rhythmical grouped discharge of tremor rhythm. Conclusions. Gamma thalamotomy for functional disorders is still under development, but because the results with careful target planning are satisfactory, there are grounds for increasing optimism.

Neuroleptic drugs cause many forms of extra-pyramidal syndromes. One of these, tardive dyskinesia,1 occurs only after the patient has been taking the drug for some time (‘tardive’ refers to the late onset). The movements are involuntary and repetitive usually involving the face and tongue, but they may also affect the limbs and trunk. Tongue protrusion, licking and smacking of the lips, sucking and chewing movements, grimacing, grunting, blinking and furrowing of the forehead have all been described and attributed to long-continued medication with neuroleptic drugs of the phenothiazine, butyrophenone and thioxanthene groups. The patient can inhibit the movements, but anxiety makes them worse. Many of these symptoms were noticed in schizophrenic patients before neuroleptic drugs were introduced2 and they can occur in otherwise normal untreated elderly people. Nevertheless it is generally accepted that in most cases tardive dyskinesia is an unwanted effect of neuroleptic medication. Despite suggestions to the contrary, the abnormal movements are not necessarily associated with high dosage of neuroleptic drugs or with pre-existing brain damage.3 4 Tardive dyskinesia has been reported in 3–6% of a mixed population of psychiatric patients5 and over half of a group of chronic schizophrenics on long-term treatment.4 The more careful the neurological examination, the greater the apparent incidence.

Initial Symptoms

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a neuroinflammatory condition mediated by autoantibodies against the GluN1 subunit of the receptor. Clinically, it is characterized by a complex neuropsychiatric presentation with rapidly progressive psychiatric symptoms, cognitive deficits, seizures, and abnormal movements. Isolated psychiatric manifestations of anti-NMDAR encephalitis are rare and usually dominated by psychotic symptoms. We present a case of an 18-year-old female high school student—without a previous history of psychiatric disorders—with a rapid onset severe depressive syndrome. Surprisingly, we found pleocytosis and anti-NMDAR autoantibodies in the cerebrospinal fluid (CSF), despite an otherwise unremarkable diagnostic workup, including blood test, clinical examination, and cranial magnetic resonance imaging (MRI). After intravenous immunoglobulins treatment, a complete remission of the initial symptoms was observed. In a follow-up 5 years later, the young woman did not experience any relapse or sequelae. Anti-NMDAR encephalitis can present in rare cases as an organic disorder with major depressive symptoms without distinct concomitant psychotic or neurological symptoms. A clinical presentation such as a rapid onset of symptoms, distinct disturbance in the thought process, restlessness, and cognitive deficits should prompt screening for NMDAR- and other neural autoantibodies to rule out this rare but debilitating pathology.

IgLON5 antibodies are typically associated with the insidious onset of sleep disorder, parasomnia, gait disturbance and abnormal movements, with variable response to immunosuppressive therapy. We describe a case of a 50-year-old man who presented with acute speech difficulties, headache and focal seizures followed by well-formed visual hallucinations, and later, musical hallucinations of mainstream popular music. MRI of the brain demonstrated right temporal lobe changes with corresponding epileptiform activity seen on electroencephalogram. Subsequently, IgLON5 antibodies were detected in the serum. The patient was treated with anticonvulsants, as well as azathioprine with a tapering oral prednisone course with a complete resolution of the symptoms. Our case demonstrates an unusual presentation of the rare but increasingly described anti-IgLON5 disease, with musical hallucinations. The case highlights the variable and evolving clinical phenotypes that can be seen in autoimmune central nervous system disorders.
