Brand new literature towards pathophysiology and the symptomatic and you will healing facets from cobalamin lack are assessed
Vitamin Bseveral deficiency has long been associated with a wide variety of hematological, neurological, and psychiatric disorders. The role of vitamin B12 deficiency as one of the few treatable causes of dementia, however, is still controversial. The authors report on 2 elderly patients suffering from cognitive impairment and psychotic symptomatology probably related to cobalamin deficiency, who showed improvement after parenteral vitamin B12 substitution.
Alzhiemer’s disease was a normally going on problem, particularly in the elderly people. The newest differential medical diagnosis of the dementia syndromes is sold with a large number from conditions, off Alzheimer’s and you can alcohol alzhiemer’s disease so you’re able to posttraumatic and you may vascular alzhiemer’s disease. Hypovitaminosis is just one of the pair problems causing dementia which can be possibly curable today.
Dementia Associated with the Vitamin B12 Deficiency
The following two case kyrgyzstan mobile chat room reports illustrate the importance of vitamin B12 deficiency as a possible cause for the development of dementia. They also underline that vitamin B12 deficiency is a frequent condition in the elderly population that is often overlooked in clinical practice. Whereas common routine parameters like the serum level of vitamin B12 or the Schilling test in deficiency, newer functional assays in B12 deficiency as a cofactor for dementia in the future.
Situation Account
Diligent 1. Patient O.F., men, is known a medical facility within period of 64 years on account of distress and failure. Based on loved ones and colleagues away from works, O.F. had revealed a slower modern transform of behavior and break down off working results as the a management staff along side early in the day five years.

Physical examination revealed a pale and dry skin and emphysematic lungs. The neurological examination showed diminished tendon reflexes and a reduced sense of posture and vibration of the legs. Primitive reflexes (palmomental and snout reflexes) were positive. CT scan and MRI of the brain showed a generalized cerebral atrophy. EEG, cerebrospinal fluid, Doppler sonography of the cerebral arteries, and xenon SPECT for the measurement of cerebral blood flow did not show any abnormalities. The serum vitamin B12 level was in the lower normal range (307 pg/ml). The red blood count was normal. The Schilling test was pathological (9% absorption of cobalamin), but normalized after substitution of intrinsic factor (18% absorption), indicating a lack of intrinsic factor. Gastroscopy revealed atrophic gastritis, which was confirmed by biopsy. Serum titers of antibodies specific for parietal cells were not elevated, however.
Detailed psychological testing (complete Wechsler Adult Intelligence Scale–Revised, Benton Visual Retention Test, Trail Making Test, and Mini-Mental State Examination [MMSE]) reflected an average overall IQ (102). Concentration and the ability to solve complex cognitive tasks were reduced, however. At the retest approximately 5 weeks later (under substitution of vitamin B12 and additional therapy with doxepin and lorazepam), the patient showed a significantly better performance IQ (112) and improved cognitive speed.
Patient 2. Patient A.H., male, was admitted to our psychiatric clinic at the age of 77 years. For the previous 13 years he had had the delusional fear of impoverishment. However, when he encountered special offers, he bought unnecessary amounts of cheap and often useless items, which he then collected in his apartment.
