Importance: Congenital Zika syndrome virus infection is said to interfere in children's development. Objective: evaluate gross motor trajectories and the frequency of cerebral palsy in children with congenital Zika syndrome. Design: Cohort study applying the Alberta Infant Motor Scale (AIMS) and the Bayley III Scales in infants from 6 to 18 months of age. Setting: The SARAH network, Rio de Janeiro. Participants: Thirty-nine infants whose diagnoses were established through clinical history, serology tests, and neuroimaging findings. Main outcomes and measures: Congenital Zika syndrome is associated with severe motor delays and is a risk factor to the diagnosis of cerebral palsy. Results: The Alberta Infant Motor Scale mean raw score at 6 months was 9.74 (SD 4.80) or equivalent to 2 to 3 months of motor developmental age. At the age of 12 months, 14.13 (SD 11.90), corresponding to 3 to 4 months of motor development age; the Bayley III Scales results correlated to the Alberta Infant Motor Scale (P < .001) at this age. At 18 months, 15.77 (SD 13.80) or a motor development equivalent to 4 to 5 months of age. Thirty-five of 39 children (89.7%) met criteria for the diagnosis of cerebral palsy. Conclusions and relevance: Gross motor development marginally progresses from 6 to 18 months of age. These individuals also displayed a high frequency of cerebral palsy.

Amyotrophic lateral sclerosis (ALS), Charcot’s disease or Lou Gehrig’s disease, is a term used to cover the spetrum of syndromes caracterized by progressive degeneration of motor neurons, a paralytic disorder caused by motor neuron degeneration. Currently, there are approximately 25,000 patients with ALS in the USA, with an average age of onset of 55 years. The incidence and prevalence of ALS are 1-2 and 4-6 per 100,000 each year, respectively, with a lifetime ALS risk of 1/600 to 1/1000. It causes progressive and cumulative physical disabilities, and leads to eventual death due to respiratory muscle failure. ALS is diverse in its presentation, course, and progression. We do not yet fully understand the causes of the disease, nor the mechanisms for its progression; thus, we lack effective means for treating this disease. In this chapter, we will discuss the diagnosis, treatment, and how to cope with impaired function and end of life based on of our experience, guidelines, and clinical trials. Nowadays ALS seems to be a more complex disease than it did two decades – or even one decade – ago, but new insights have been plentiful. Clinical trials should be seen more as experiments on pathogenic mechanisms. A medication or combination of medications that targets more than one pathogenic pathway may slow disease progression in an additive or synergistic fashion.

Transthyretin familial amyloid polyneuropathy is an autosomal dominant inherited sensorimotor and autonomic polyneuropathy, which if untreated, leads to death in approximately 10 years. In Brazil, liver transplant and tafamidis are the only disease-modifying treatments available. This review consists of a consensus for the diagnosis, management and treatment for transthyretin familial amyloid polyneuropathy from the Peripheral Neuropathy Scientific Department of the Brazilian Academy of Neurology. The first and last authors produced a draft summarizing the main views on the subject and emailed the text to 10 other specialists. Relevant literature on this subject was reviewed by each participant and used for the individual review of the whole text. Each participant was expected to review the text and send a feedback review by e-mail. Thereafter, the 12 panelists got together at the city of Fortaleza, discussed the controversial points, and reached a consensus for the final text.
