1.  Steroid-responsive encephalopathy in autoimmune thyroiditis: Clinical spectrum and MRI observations in three cases 
Hashimoto's encephalopathy (H.E.) is probably of autoimmune etiology, and manifests with seizures, stroke-like episodes, cognitive decline, neuropsychiatric symptoms, myoclonus. It is presumed to be autoimmune in origin with high serum titers of antithyroid peroxidase antibodies (anti-TPA). Thyroid function might often be normal. The diagnosis is arrived at by excluding other toxic, metabolic and infectious causes of encephalopathies, supportive clinical profile, elevated thyroid antibodies and optimum steroid response. We present the characteristic phenotypic manifestations, magnetic resonance imaging and electroechography observations and response to immunomodulation with follow-up in three cases of H.E. All the three cases manifested with subacute to chronic progressive encephalopathy, cerebellar dysfunction, seizures, behavioral abnormalities and oculomotor disturbances and had evidence of hypothyroidism, elevated titers of anti-TPA and positive thyroid anti-microsomal antibodies. Atypical and uncommon presentations are known. This report emphasizes that a high index of suspicion is often required in cases with “investigation negative encephalopathy” for early diagnosis of H.E.

4.  Guillain-Barré syndrome following snake bite: An unusual complication 
A 40-year-old man presented with a nonhealing wound on the left ankle for the last 5 weeks, a tingling sensation in both hands for 20 days, and weakness in all four limbs for 10 days. He had been bitten by a snake while working in a sugarcane field 6 weeks earlier and had received tetanus toxoid and anti–snake venom on the day of the bite. He had clinical, biochemical, and electrophysiological features of Guillain-Barré syndrome, with motor and sensory neuropathy—primarily suggestive of demyelination with secondary axonal degeneration. Recognition of this unusual complication following snake bite or use of anti–snake venom / tetanus toxoid has considerable epidemiological, therapeutic, and prognostic significance.

5.  Quality of life and psychological problems in patients undergoing neurological rehabilitation 
To assess the quality of life (QoL) and prevalence of psychological problems (PP) in patients with neurological illness, and their correlation with functional abilities.
Materials and Methods:
Prospective cross-sectional study conducted in the neurological rehabilitation unit of tertiary research hospital in 30 consecutive hospitalized patients (21 men), age 16-55 years (34.63±11.87).
Outcome Measure:
WHOQoL-BREF was used to assess QoL. The prevalence of PP was recorded using Hospital Anxiety Depression Scale (HADS) and General Health Questionnaire (GHQ-12). QoL and HADS scores were correlated with functional abilities using mean Barthel Index (BI) Score.
The duration of illness was three to 30 months (10.63±7.83) and their primary diagnoses were stroke 12, traumatic spinal cord injury seven and non-traumatic spinal cord lesion 11. Twenty-two patients qualified for GHQ-12 caseness, with 15 patients having distress (score ≥15) and seven having severe problem and psychological distress (score≥20). Twenty five patients had abnormal anxiety and 17 had abnormal depression on HADS (abnormal = 8-21), with moderate to severe anxiety and depression (scores≥11) in nine and three patients respectively. The mean WHOQoL-BREF transformed scores (on WHOQoL 0-100 scale) were (38.83±8.02), (50.76±9.79), (48.53±18.46) and (49.13±10.63) in physical, psychological, social, and environmental domains respectively. The social domain of QoL had significant correlation (P<.05) with functional abilities.
Patients with neurological disorders requiring inpatient rehabilitation have impaired QoL that affects all domains of life. There is high prevalence of psychological problems, including anxiety and depression. The social domain of QoL adversely affected functional abilities, but the correlation between PP and functional abilities was insignificant.

7.  Myasthenia gravis and acetylcholine receptor antibodies: A clinico immunological correlative study on South Indian patients 
Acquired myasthenia Gravis (MG), a disorder of impaired neuromuscular transmission is recognized as an autoimmune disorder, with a majority of the patients having antibodies against acetylcholine receptor (AChR antibodies) in the serum.
Aim and Objectives:
To correlate the AChR antibody status with the clinical characteristics of patients with myasthenia gravis.
Study Design:
Retrospective and prospective study.
Materials and Methods:
This study was carried out in patients with definite MG, attending the Neurology services of the National Institute of Mental Health and Neurosciences, Bangalore, India, during the period 1999-2003. The AChR antibody status was determined using the direct and indirect enzyme linked immunosorbent assay (ELISA) technique.
There were 165 patients in this study (M : F :: 1.5 : 1). The overall seropositivity rate was 59.4%. Seropositive patients had higher age of onset and presentation, and more frequent occurrence of crises, both at presentation and at any time during the course. Other parameters, viz. gender of the patient, Osserman staging, thymic enlargement on CT and remission during follow-up did not differ between the two groups.
This communication reports the result of AChR antibody assay in a large cohort of patients, using a simple diagnostic tool, namely direct and indirect ELISA technique. In addition, the characteristics of a large cohort of patients with seronegative myasthenia gravis are described.

8.  Quality of life in Wilson's disease 
Assessment of Quality of life (QoL) is fast assuming significance as the measure of health in many disorders.
To correlate clinical severity and QoL in patients with Wilson's disease (WD).
Materials and Methods:
We evaluated patients of WD on regular follow up for at least two years and aged over 18 years using Neurological Symptom Score (NSS) for clinical severity and WHO-BREF for QoL at a university teaching hospital. Patients with inability to respond to the questionnaire due to behavioral problems, low IQ or other disease related factors were excluded. These 30 patients (M:F:: 23:7) had a mean age of 27.97 ± 11.16 years at evaluation and the mean duration of treatment of 9.2 ± 6.4 years.
All four domains of WHO-QoL-BREF viz., Physical, Psychological, Social and Environmental correlated well with each other (p < 0.01). The NSS correlated inversely with the physical domain (p < 0.02), while the duration of treatment had a positive correlation with the physical domain (p < 0.01). None of the other features of QoL showed any significant correlation with age, NSS or duration of treatment.
QoL is complementary to formal neurological assessment and should be routinely incorporated in the evaluation of outcome of patients with WD and other chronic neurological disorders.
