The nerves supplying the spinal dura mater were studied in four human foetuses (16-22 weeks) with the acetylcholinesterase in toto staining method. The ventral spinal dura contains a dense, longitudinally oriented, nerve plexus, which receives its contributions from: (I) the sinuvertebral nerves, (II) the nerve plexus of the posterior longitudinal ligament, (III) the nerve plexus of radicular branches of segmental arteries. Dorsal dural nerves are much smaller in number, do not form an evident plexus and do not reach the medial region of the dorsal dura. The dorsal nerves are derived from the ventral dural plexus at the level of the "intersleeval" parts of the dura mater. The ventral dural nerves may extend up to eight segments, with a great amount of overlap between adjacent nerves. This may provide an anatomical substrate for the understanding of extrasegmentally referred dural pain. The curled bundles of nerve fibres of pathways (I) and (II) provide an adequate adaptation to displacements of the spinal dura mater during flexion and extension. Pathway (III) has not been described before. The described nerve plexuses may be of importance in elucidating the mechanisms of epidural therapies in back pain and peripheral vascular disease.

There is a growing body of evidence that the central nervous system (CNS), even in the adult animal, is capable of adaptation and reorganization not only as a result of partial damage to the CNS but also in response to stimulation. Environmental stimulation produces changes including expansion of visual cortex, increases in dendritic branching, glia and cholinesterase. Environmental stimulation also produces behavioural changes. Experimental electrical stimulation produces changes in synapse size, synaptic vesicle change, dendritic branching and changes in synaptic transmission. In man, repetitive electrical stimulation via epidural electrodes increases plasma levels of norepinephrine, epinephrine, and dopamine, and CSF levels of norepinephrine. Repetitive electrical stimulation in man dates back to 1967 and has been used for the control of pain, to improve spasticity, bladder control, motor deficit and the autonomic hyperreflexia of spinal cord injury. In addition, improvement has been reported in epilepsy, cerebral palsy, torticollis and peripheral vascular diseases. The best controlled studies are in multiple sclerosis and peripheral vascular disease, and these results will be presented in more detail.

Ischemic or hemorrhagic cerebrovascular disease (CVD) produces injury of brain regions important for executive function, behavior, and memory leading to decline in cognitive functions and vascular dementia (VaD). Cardiovascular disease may cause VaD from hypoperfusion of susceptible brain areas. CVD may worsen degenerative dementias such as Alzheimer disease (AD). Currently, the global diagnostic category for cognitive impairment of vascular origin is vascular cognitive disorder (VCD). VCD ranges from vascular cognitive impairment (VCI) to VaD. The term VCI is limited to cases of cognitive impairment of vascular etiology, without dementia; VCI is equivalent to vascular mild cognitive impairment (MCI). Risk factors for VaD include age, hypertension, diabetes, smoking, cardiovascular disease (coronary heart disease, congestive heart failure, peripheral vascular disease), atrial fibrillation, left ventricular hypertrophy, hyperhomocysteinemia, orthostatic hypotension, cardiac arrhythmias, hyperfibrinogenemia, sleep apnea, infection, and high C-reactive protein. Research on biomarkers revealed increased CSF-NFL levels in VaD, whereas CSF-tau was normal. CSF-TNF-alpha, VEGF, and TGF-beta were increased in both AD and VaD. VaD shows low CSF acetylcholinesterase levels. This condition responds to acetylcholinesterase inhibitors, confirming the central role of cholinergic deficit in its pathogenesis. Evidence strongly suggests that control of vascular risk factors, in particular hypertension, could prevent VaD.
