Background: Central nervous system (CNS) disorders are a group of neurological disorders concerned with behaviour, coordination and functioning of the brain and the spinal cord. The CNS is the site of processing various informations. It interprets and evaluates the information and as result, the CNS responds accordingly and controls the body. Any defects or disorders of the Central nervous system may cause degeneration of the organs and tissues associated with it, loss of coordination, paralysis, etc. These disorders may be hereditary or due to injuries to the brain and spinal cord. Although, these disorders are being cured with medicaments, many plant species are also seen to be effective in its treatment. Objective: the main objective of this article is to underline the potentials and the needs for the documentation of the ecological knowledge of herbal medicines of the north east India region, necessary for the greater well-being of mankind in the prevention and cure of CNS disorders. Methods: an extensive literature survey was carried out through various databases like Google Scholar, Pubmed, Sciencedirect etc to support this review. All the collected information was analyzed accordingly and the plants were enlisted based on the classes of CNS disorders for which they are used. Result and discussion: from the survey of the database being collected, it was found that many traditional and local plants of the northeast India region are therapeutically effective in the treatment and cure of many Central nervous system disorders. Conclusion:-It is now an accepted fact that many traditional plants found in the Northeast India have been acceptable within the human body and hence these can be used to replace many expensive medications available in the market.

Central nervous system (CNS) disorder is the world’s leading cause of disability and account of more hospitalizations. Central nervous system disorders are a group of neurological disorder that affect the structure or function of the brain or spinal cord. Depression (major depressive disorder or clinical depression) is a common but serious mood disorder. It causes severe symptoms that affect how you feel, think, and handle daily activities, such as sleeping, eating, or working. The aim of treatment is release of neurotrophic proteins in the brain that can help to rebuild the hippocampus that has been reduced due to depression and to optimize patients’ physical, psychological and social functioning. This review presents a brief summary on psychological implications of living with depression, pathogenesis, diagnosis, causes, sign and symptoms and treatments associated with depression.

Abstract Injuries that affect the central nervous system (CNS) can be catastrophic because they involve the brain or spinal cord, and determining the underlying clinical cause of impairment is essential in using the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), in part because the AMA Guides addresses neurological impairment in several chapters. Unlike the musculoskeletal chapters, Chapter 13, The Central and Peripheral Nervous System, does not use grades, grade modifiers, and a net adjustment formula; rather the chapter uses an approach that is similar to that in prior editions of the AMA Guides. The following steps can be used to perform a CNS rating: 1) evaluate all four major categories of cerebral impairment, and choose the one that is most severe; 2) rate the single most severe cerebral impairment of the four major categories; 3) rate all other impairments that are due to neurogenic problems; and 4) combine the rating of the single most severe category of cerebral impairment with the ratings of all other impairments. Because some neurological dysfunctions are rated elsewhere in the AMA Guides, Sixth Edition, the evaluator may consult Table 13-1 to verify the appropriate chapter to use.

At a quarterly meeting of this Association held last year at Nottingham, we showed the results of our experiments with toxins upon the spinal cord and brain of rabbits. Our main conclusion was, that the central nervous system could be infected by toxins passing up along the lymph channels of the perineural sheath. The method we employed in our experiments consisted in placing a celloidin capsule filled with a broth culture of an organism under the sciatic nerve or under the skin of the cheek; and we invariably found a resulting degeneration in the spinal cord or brain, according to the situation of the capsule. These lesions we found to be identical in morphological type and anatomical distribution with those found in the cord of early tabes dorsalis and in the brain and cord of general paralysis of the insane. The conclusion suggested by our work was that these two diseases, if toxic, were most probably infections of lymphogenous origin.

The central nervous system develops from a proliferating tube of cells and retains a tubular organization in the adult spinal cord and brain, including the forebrain. Failure of the neural tube to close at the front is lethal, whereas failure to close the tube at the back end produces spina bifida, a serious neural tube defect. Swellings in the neural tube develop into the hindbrain, midbrain, diencephalon, and telencephalon. The diencephalon sends an outpouching out of the cranium to form the retina, providing an accessible window onto the brain. The dorsal telencephalon forms the cerebral cortex, which in humans is enormously expanded by growth in every direction. Running through the embryonic neural tube is an internal lumen that becomes the cerebrospinal fluid–containing ventricular system. The effects of damage to the spinal cord and forebrain are compared with respect to impact on self and potential for improvement.

Adiponectin, the most abundant plasma adipokine, plays an important role in the regulation of glucose and lipid metabolism. Adiponectin also possesses insulin-sensitizing, anti-inflammatory, angiogenic, and vasodilatory properties which may influence central nervous system (CNS) disorders. Although initially not thought to cross the blood-brain barrier, adiponectin enters the brain through peripheral circulation. In the brain, adiponectin signaling through its receptors, AdipoR1 and AdipoR2, directly influences important brain functions such as energy homeostasis, hippocampal neurogenesis, and synaptic plasticity. Overall, based on its central and peripheral actions, recent evidence indicates that adiponectin has neuroprotective, antiatherogenic, and antidepressant effects. However, these findings are not without controversy as human observational studies report differing correlations between plasma adiponectin levels and incidence of CNS disorders. Despite these controversies, adiponectin is gaining attention as a potential therapeutic target for diverse CNS disorders, such as stroke, Alzheimer’s disease, anxiety, and depression. Evidence regarding the emerging role for adiponectin in these disorders is discussed in the current review.

Abstract Twenty-one patients with recurrent malignant central nervous system gliomas were treated with a combination of 5-fluorouracil, CCNU, hydroxyurea, and 6-mercaptopurine. Thirteen patients had brain stem gliomas, 3 patients had spinal cord gliomas, 3 patients had thalamic gliomas, and 2 patients had cerebellar astrocytomas. All patients had received radiation therapy, and 4 brain stem patients had also been treated with chemotherapy. Sixteen patients (76%) responded to treatment with either stabilization of disease or improvement. Nine of the 13 patients with brain stem gliomas (71%) had response or stabilization of disease. The median time to tumor progression (TTP) for the brain stem patients who responded or had stabilization of disease was 25 weeks. The median survival from recurrence for the brain stem glioma patients was 27 weeks. Patients with cerebellar, thalamic, and spinal cord tumors did very well, with an 87% response or stabilization of disease and a median TTP of 122 weeks.

The expression of prosaposin is temporally and spatially regulated at transcriptional and post-translational levels. Transgenic mice with various 5′-flanking deletions of the prosaposin promoter fused to luciferase (LUC) reporters were used to define its temporal regulatory region. LUC expression in the transgenic mice carrying constructs with 234bp (234LUC), 310bp (310LUC) or 2400bp (2400LUC) of the 5′-flanking region was analysed in the central nervous system and eye throughout development. For 310LUC and 2400LUC, low-level LUC activity was maintained until embryonal day 18 in brain, eye and spinal cord. The peak level of LUC activity was at birth, with return to a plateau (1/3 of peak) throughout adulthood. Deletion of the region that included the retinoic acid-receptor-related orphan receptor (RORα)-binding site and sequence-specific transcription factor (Sp1) cluster sites (44—310bp) suppressed the peak of activity. By comparison, the peak level for 234LUC was shifted 2 weeks into neonatal life in the brain, but not in the eye, and no peak of activity was observed in the spinal cord. The endogenous prosaposin mRNA in eye, spinal cord and cerebellum had low-level expression before birth and continued to increase into adulthood. In cerebrum, the endogenous mRNA showed similar expression profile to constructs 310LUC, 2400LUC and 234LUC, with the peak expression at 1 week and a decreased level in adult. In the brain of the newborn, 2400LUC was highly expressed in the trigeminal ganglion and brain stem regions when compared with the generalized expression pattern for endogenous prosaposin mRNA. These results suggest that the modifiers (RORα- and Sp1-binding sites) residing within 310bp of the 5′-flanking region mediate developmental regulation in the central nervous system and eye. Additional regulatory elements outside the 5′ region of the 2400bp promoter fragment appear to be essential for the physiological control of the prosaposin locus.

The specimens submitted for examination were:(a) Portions of the brain (labelled Specimen XXXI.).(b) Portions of spinal cord (labelled Specimen XXIV.).Both were in excellent condition as regards fixation and hardening, having been preserved for many years in a fluid composed of formol and 95 per cent. alcohol (the fluid was also injected into the cerebral vessels). They were, previous to histological examination, submitted to the following processes:—i. Comparatively thin slices were taken from various regions and placed for twenty-four hours in absolute alcohol.ii. Then transferred to acetone for twelve hours.iii. Placed in xylol until permeated.iv. Embedded in paraffin of melting-point 52° C. Sections were then taken with an improved form of the Cambridge rocking microtome, and fixed to slides by means of the albumen method.

✓ The kinetics of distribution of 3H methotrexate (3HMTX) in the central nervous system, plasma, and urine after intraventricular, lumbar percutaneous puncture, and spinal catheter injections were compared. Levels of 3HMTX in whole brain after lumbar percutaneous injection were 40 times less than after intraventricular injection. Injection of 3HMTX via a spinal catheter increased the level of 3HMTX in whole brain but this was still tenfold less than after direct intraventricular instillation. Also, it was found that a disproportionately high amount of 3HMTX was in the brain-stem-cerebellum region which would further reduce the concentration of methotrexate in the cerebral hemispheres. Both intraventricular and lumbar spinal catheter administration of 3HMTX produced 3HMTX levels greater than 10−6M (moles/kg wet weight) in spinal cord tissue as measured by 3H specific activity between 2 to 8 hours after injection. Administration by lumbar percutaneous puncture, however, rarely resulted in this suggested therapeutic level of 10−6M. Initial 3HMTX levels in plasma after lumbar percutaneous instillation was 24 times greater than after intraventricular or lumbar spinal catheter injections. This indicated significant and unavoidable extradural leakage after lumbar percutaneous puncture, which may account for the substantially lower levels of 3HMTX in the brain and spinal cord tissue. It is concluded that intraventricular instillation of methotrexate is the best route of administering the drug to achieve therapeutic levels of methotrexate in both whole brain and throughout the spinal cord.
