Abstract
Since the early descriptions of diabetic neuropathy, many attempts
of classification have been tried. Pryce in (1893)(1•‹), suggested a
subdivision into two categories: a patchy motor type, and a sensory or
ataxic type.(2). Sullivan in (1958), advocated two types of neuropathies:
asymmetrical, painful and predominantly motor type and the second type
was a symmetrical, distal, and predominantly sensory neur~pathy(~~’. Fry
and Co-worhers (1962), classified their cases into three categories:
comprising a symmetrical sensory neuropathy; diabetic amyotrophy, and
isolated peripheral nerve lesions(26), to which Gilliatt in 1965, added an
additional category of autonomic n e u r ~ ~ a t h y ’ ~ ~ .
Bruyn and Garland in (1970), tried to synthesize the various
suggested classification proposed up until now, as indicated in Table 1”).
Thomas in( 1973), advocated a broad subdivision into symmetrical
polyneuropathies on one hand and focal and multifocal neuropathies on
the other Table 2””. The first category includes the symmetrical sensory
polyneuropathy and autonomic neuropathy. The justification for including
autonomic neuropathy in this category is the very precise symmetry of
involvement(14). Furthermore, there is a fairly close association between autonomic neuropathy and sensory ne~ropathy”~). In the second category
of focal and multifocal neuropathies are isolated lesions of the cranial
nerves and focal neuropathies affecting trunk and limb nerves(29).
