Classification of diabetes neuropathy [adapted from Pop-Busui et al. (2)].

I. DIFFUSE NEUROPATHY
A. Distal symmetrical polyneuropathy (DSPN)
	i) Primary large fibre involvement
	ii) Primarily small fibre involvement
	iii) Mixed large and small fibre involvement (commonest)
B. Autonomic neuropathy
	i) Cardiovascular Resting tachycardia Orthostatic hypotension Reduced heart-rate variability Malignant arrhythmias
	ii) Gastrointestinal Diabetes gastropathy Diabetes enteropathy Colonic dysmotility
	iii) Urogenital Erectile dysfunction Neurogenic bladder Female sexual dysfunction
	iv) Sudomotor dysfunction Gustatory sweating Distal hypohydrosis
	v) Hypoglycaemic unawareness
	vi) Pupillary abnormalities
II. Mononeuropathy (mononeuritis multiplex)
A. Isolated cranial nerve (III/VI) palsy
B. Peripheral nerve palsies (ulnar, median, femoral, peroneal)
C. Mononeuritis multiplex
III. Radiculopathy or polyradiculopathy
A. Radiculoplexus neuropathy (lumbosacral radiculopathy, diabetes amyotrophy)
B. Thoracic radiculopathy
