In a retrospective study 134 galactosaemic patients, born between 1955 and 1989 in the Federal Republic of Germany were traced and their long-term outcome evaluated. We investigated 83 galactosaemic patients (78 homozygotes, 5 compound heterozygotes) by clinical, psychometric and laboratory testing; 31 patients were evaluated by medical history, the remaining 20 patients had died due to sequelae of the underlying disease. In 48 out of 78 classical galactosaemia patients galactose-free therapy had been started before the 15th day, in 19 between days 15 and 56 and in 11 patients after the 56th day. Physical findings revealed that puberty was delayed in 1 out of 18 males and 6 out of 11 females. Neurological abnormalities included ataxia (n = 6), intention tremor (n = 11) and microcephaly (n = 10). Speech abnormalities were found in 43 out of 66 patients over 3 years of age and disturbance of visual perception and/or arithmetic deficits in 29. Intelligence declined with age, i.e., a DQ or IQ less than 85 was found in 4 out of 34 patients less than 6 years of age (12%), in 10 out of 18 between 7 and 12 years (56%) and in 20 out of 24 older than 12 years (83%). Metabolite patterns (RBC galactose-1-phosphate and UDP-galactose, plasma and urinary galactitol) did not correlate with DQ or IQ. Dietary compliance was good in almost all patients. Compound heterozygotes (n = 5) had normal mental and growth development and all laboratory parameters were in the normal range.(ABSTRACT TRUNCATED AT 250 WORDS)

Speech and language disorders are prominent signs in Friedreich ataxia (FRDA), which significantly impact on patients' quality of life. Despite such relevance, several issues regarding phenomenology, assessment, and treatment are still unmet. In this short review, we thus analyzed the existing literature to summarize what is known about the features of speech and language disorders in FRDA, which methods are used for evaluation and rating, and what are the available therapeutic strategies and future direction of scientific research in this field, in order to highlight critical aspects for a better clinical approach to the problem. FRDA patients often present dysarthria, resulting from central and peripheral causes and additional primary language disorders. Speech disturbances have peculiar characteristics, although variable among patients, and progress along the disease course. Assessment relies on multiple but not specific clinical scales, some of which can also reflect the general severity of ataxia; classical instrumental investigations and novel technologies allow more accurate measurements of several speech parameters, which could found application as potential disease's biomarkers. No successful treatments exist for communication disorders of FRDA patients; however, the tailored speech training or the non-invasive neuromodulation appear as the most reliable therapeutic options to be validate in future trials.
