RESUMO
The reduction of working ability, because of disease, was considered in 1,053 subjects. 21 groups of maladies were found; the neurological disease and mental retardation (MR) caused various degrees of working inability in 416 subjects, i.e. in the 39.51% of the examined population; orthopaedic changes affected the 15.57% of the patients; psychic disorders determined some inability in 8.93% of the persons. The subjects unable to work receive, by Law, an economic help. This study was limited to neurological patients and to subjects mentally retarded. The working ability was reduced by 5 types of disturbances: neuromotor pathology, mental retardation, mental deterioration and dementia, epilepsy, other neurological diseases. The neuromotor pathology affected 163 subjects; the types of symptomatology: hemiplegia; it was found in 71 patients; 62 times it was the result of cerebrovascular disease; in 4 patients it was caused by a hypoxic-ischaemic pre-perinatal encephalopathy. 43 patients affected by cerebrovascular disease lost their personal autonomy, i.e. they could no longer do the activities of daily living (ADL); 7 patients lost their working ability; 12 subjects kept some ability to work. The hemiplegias which struck after 50 years of age were caused by cerebrovascular disease; paraplegia: 28 paraplegic patients have been seen; the aetiology was: poliomyelitis in 8 subjects; MS in 5 patients; ALS in 2 patients; in 13 patients the aetiology was unknown. 6 patients resulted unable to work; 8 persons kept some working ability; 14 patients lost the ability to do the ADL; tetraplegia, or double/bilateral hemiplegia, was found in 20 patients; the aetiology: poliomyelitis in 4 patients; pre-perinatal hypoxic ischaemic encephalopathy in 4 patients; 3 patients of MS; lesion of the cervical spinal cord because of breech delivery in 2 patients; the aetiology was not known in 7 persons. The ability to do the ADL was lost in 17 patients; 3 subjects kept some working ability. Double or bilateral hemiplegia (Little disease) was the model of neuromotor deficit subsequent natal encephalopathy (Infantile Cerebral Palsy, PCI); brachial plexus paralysis was only found from obstetrical (i.e. natal) origin; poliomyelitis and PKU resulted prevented as of 10 years. Mental Retardation (MR) was considered a borderline pathology between neurology and psychiatry; it included 162 subjects: in patients with severe MR a pre-perinatal hypoxic-ischaemic encephalopathy was found in 40.4% of the cases; in patients affected by moderate or light MR the same encephalopathy was found in the 11.3% of the subjects.(ABSTRACT TRUNCATED AT 400 WORDS)
