Expert Group Meeting on Aphasia: A Report.

A multidisciplinary team of experts took stock of the current state of affairs about many aspects of aphasia in India, including community burden, diagnostic assessment, therapy, rehabilitation, research, education, and advocacy. The broad spectrum of aphasiology was matched by the types of participants ranging from neurologists, speech-language pathologists, clinical psychologists, linguists, to experts in neuroimaging and computer sciences. Threadbare discussion in 16 sessions over 3 days leads to the identification of pressing problems and possible solutions. Many action plans have been envisaged and recommendations made. A few examples with high priority are community-based and hospital-based study incidence and prevalence of aphasia, development of test batteries for the assessment of many components of speech and communication in Indian languages which are validated on rigorous psychometric, and linguistic criteria, national registry for aphasia, educational modules about aphasia for different target groups, resources for advocacy and its training, a bank of research questions and outlines of research protocols for young professionals to pursue. The expert group will continue to oversee execution of some of the actionable plans in short and long term.

Developmental Gerstmann's syndrome: a distinct clinical entity of learning disabilities.

The symptom complex of finger anomia, right-left disorientation, dysgraphia, and dyscalculia constitutes Gerstmann's syndrome. It is mostly described in adults and is caused by acquired lesions of the dominant parietal lobe. It is infrequently described in children with learning disabilities and has been designated developmental Gerstmann's syndrome. Developmental Gerstmann's syndrome goes unnoticed if not specifically sought by clinicians. A detailed evaluation will reveal subtle neurologic deficits, behavioral problems, and neuropsychologic and specific speech and language abnormalities. Ten such patients are reported; six of the children demonstrated improvement with intensive speech training. Early identification and intervention is therefore crucial, and even more important in cultures in which students are required to be biliterate or triliterate, further increasing the constraints on writing. A selective writing, reading, or calculation abnormality in the presence of normal oral communication triggers several interesting possibilities for the brain mechanisms behind normal language processing. Similarly, the association of acalculia with finger anomia and agraphia with right-left disorientation may have specific implications in the neuropsychologic processing of the evolution of calculation and writing. A theoretical possibility of oral and written language processing from the observation of the language behavior of these children is also described.

Subclinical hyperthyroidism and hyperkinetic behavior in children.

The authors report three children who exhibited developmental learning disabilities (DLDs) associated with behavioral disturbances, such as attention deficit, hyperactivity, and autistic features. The thyroid function tests performed as a part of routine endocrinologic evaluation of children with DLDs revealed a hormonal profile consistent with hyperthyroidism. These children had no systemic signs of hyperthyroidism. Treatment with neomercazole resulted in good control of their hyperkinetic behavior and subsequent improvement in language function attributable to an increased attention span, thereby facilitating speech therapy. Although routine screening of all children with DLDs for thyroid dysfunction may not be cost-effective, selective screening of children with familial attention-deficit hyperactivity disorder and those with attention-deficit and hyperactivity in association with DLDs and pervasive developmental disorders appears to be justified.

Myasthenia gravis, motor neuron syndrome and thymoma.

An adult male with thymomatous myasthenia gravis (MG) and a motor neuron syndrome simulating amyotrophic lateral sclerosis is reported. After thymectomy and corticosteroid therapy, the MG remitted. During 4 years of follow-up, the lower motor neuronsigns in the upper limbs and upper motor neuron signs in the lower limbs remained unchanged. Literature concerning paraneoplastic neurological syndromes associated with thymoma has been reviewed.
