Extract:
A retrospective case-note analysis was undertaken of 47 children
with a congenital upper motor neurone bulbar palsy (excluding
pure speech dyspraxia) to clarify the phenotype of Worster-Drought
syndrome (WDS) and to record its associated features
and complications. The results revealed that the
study children had significant bulbar problems
(with 80% still needing a modified diet and a
similar number using augmentative communication methods at
last review). There were also high rates of predictable
bulbar complications (86% had dribbling, 60%
had glue ear, gastro-oesophageal reflux in 40%,
history of poor nutrition in 40% and aspiration in
40%). Most of the children had additional complex impairments
(91% had mild pyramidal tetraplegia, 81% learning
difficulties, 60% congenital defects, 41%
neuropsychiatric problems and 28% epilepsy).
Over half of the children had significant medical problems
in the first year, but mean age at diagnosis was 6 years.
There were no obvious causes in pregnancy or birth. Six
children had a family history of WDS and 32% (12/37)
had abnormal neuroimaging including five with bilateral
perisylvian polymicrogyria. In our experience,
WDS is not uncommon, is relatively easily diagnosed
and is crucial not to miss as the management of these
children's multiple impairments is complex and requires
a careful team approach. WDS falls clearly within
the cerebral palsies as a syndrome that includes
motor impairment arising from static damage to
the brain in early life. The common presence of cognitive,
behavioural and seizure impairments strongly supports
the cerebral cortical (presumably perisylvian)
localization. Its core elements are a suprabulbar
paresis, a mild spastic tetraplegia and a significant
excess of cognitive and behavioural impairments and
epilepsy. The complete overlap in phenotype between WDS
and the bilateral perisylvian syndrome leads us to propose
that they are the same condition. WDS is startlingly
absent from epidemiological studies of the cerebral
palsies and rarely diagnosed, presumably because
of lack of clinical awareness of the condition and
lack of major gross motor impairments.
