Improved brain function (part 2)

The cervical subluxation and regional cerebral blood flow. Sato, A and Budgell B. From the abstract: This article specifically addresses the question of whether the manipulable cervical lesion is likely to cause extrinsic compression of the vertebral arteries sufficient to cause such symptoms of reduced regional cerebral blood flow as might be relieved by spinal manipulation.
Conclusion: It has been hypothesized elsewhere at the manipulable cervical lesion may induce localized decreases in regional cerebral blood flow and so signs and symptoms attributable to "cerebral hibernation" if an etiologic relationship does exist between the cervical subluxation and reduced regional cerebral blood flow, it is not likely to be due to mechanical compression to the vertebral arteries.


Dr. Koren: Dr. Frank Gorman hypothesized that the reason why patients visual acuity and other conditions improved after spinal care was due to removed blockage of the vertebral arteries. Dr. Alan G. J. Terrett's paper on brain hibernation (Cerebral dysfunction: A theory to explain some effects of chiropractic manipulation. Terrett AGJ. Chiropractic Technique; 1993; 5:168-173) discusses vertebral artery blockage as one possible mechanism of action. However he has written that there may be more to the decrease in cerebral blood flow due to cervical spine subluxation than blockage of the cerebral arteries. In answering criticism that blockage of the cerebral arteries could not induce "brain hibernation" Dr. Terrett did in fact agree that the cerebral arteries may not be the mechanism of the reduced cerebral blood flow due to cervical subluxation and that there may be, and most likely were other mechanisms involved. As Dr. Terrett has written:

The cortex is not the whole deal anyway, the brainstem is not without important (blood supply from the vertebral arteries), and without it, the cortex is isolated anyway. In this paper I did not address the possibility of diaschisis. It is not practical or sensible to separate the brain into sections relating to blood supply apart from the consideration of major segmental catastrophes, such as stroke. Letter to the editor. Terrett AGJ. Chiropractic Technique Vol/6. No.3, August 1994.

Sato and Budgell's paper further indicates that the vertebral arteries may not be the mechanism of cerebral function compromise which appears to occur due to vertebral Subluxations. This fascinating field will no doubt uncover other mechanisms of spinal/brain relationship and I hope research in this field continues. However let's not forget that the mechanism of function is of secondary importance. As with all Empirical healing arts (of which chiropractic is one) the most important thing is whether or not the patient gets better, not how well the mechanism is understood.


Study on cervical visual disturbance and its manipulative treatment. Zhang C, Wang Y, Lu W, et al. J Trad Chinese Medicine, 1984; 4:205-210.
From the abstract: "Determination of blood flow by x-ray in 18 of our cases shows that blood flow of the cerebral hemispheres greatly improves after manipulative treatment. The same is true in similar animal tests."


Impaired Arterial Blood Flow to the Brain as result of a cervical subluxation: a clinical report. Risley, WB. Journal of the American Association/June 1995. Pp. 61-63.
From the abstract: The author has witnessed impairment of the velocity of arterial blood flow of the occipital artery, unilaterally or bilaterally, as a direct result of a cervical subluxation in over 15,000 patients. This impairment is documented by Doppler examination and is the virtual 100 percent concomitant of a cervical subluxation. Clinical correction of the subluxation, especially at the C-1, C-2 level, restores the blood velocity through the occipital artery, virtually 100 percent of the time. Failure to correct the subluxation commonly fails to relieve the impaired blood velocity in this artery. It is thus an effective monitor of the efficacy of the administered adjustment.


Course of attention and memory after common whiplash: a two-year prospective study with age, education and gender pair-matched patients. Di Stefano G and Radanov BP ACTA Neurol Scand 1995; 91 436-352).
From the abstract: "Attentional functional and memory of common whiplash patients were evaluated during the first two years after experiencing injury. All (117) patients had a similar socioeconomic background; all being injured in automobile accidents and fully covered by insurance plans. Two years following initial trauma, 21 patients remained symptomatic."

When compared with matched controls, the 21 symptomatic patients had no memory impairment but did have attention functional (difficult of follow-up of tasks with divided attention). Comment: Some studies have documented attention deficits in symptomatic whiplash patients as well as memory loss while other studies have not. This paper reviews the value of the studies done by others in this field and found them to have designs that were "insufficient." The Chiropractic interest in this subject is more than that is affected by presumed subluxations of the cervical spine. This work should be read in concert with Gorman's and Zhang's papers (above).


Automated static perimetry in chiropractic. Forman RF. JMPT 1993; 16: 481-487.
Author's Abstract: A 44-year-old housewife presented with non-specific bilateral visual field loss. This visual disability disappeared immediate to pan-spinal manipulation under anesthetic. Later, on review, the presence of an uni-ocular visual defect was detected by quantitative static perimetry. Further examination revealed no pathology in the eye or brain to explain its occurrence, suggesting that is was due to micro-ischemia of the optic nerve.
Intervention and outcome: The uni-ocular scotoma recovered immediate to further spinal manipulation under anesthetic, only to recur on two further occasions, each time to disappear immediate to spinal treatment.
Conclusions: This case history demonstrates that spinal manipulation may dissipate microvascular spasm in the brain: even in branches of the carotid arterial system, which is not directly related to the spine.


Mild head injury in preschool children: evidence that it can be associated with a persisting cognitive defect. Wrightson P. McGinnV, Gronwall D. J Neurol Neurosurg Psychiatry 1995; 59:375-380.
Mild head injury was defined by a hospital emergency department as a head injury no severe enough to need admission for observation. 78 children were compared with 86 controls who had a minor injury in other areas. Children with mild head injury, at six months and one year were found to have scored less on a visual puzzle test and were more likely to have another mild head injury. At 6.5 years they still scored less than controls.


Panic Attacks and the chiropractic adjustment: a case report. Potthoff S. Penwell B, Wolf J. ACA J of Chiropractic, 1993 (December) 30:26-28. A 52-year-old female diagnosed with chronic panic attacks. She had been prescribed a variety of antidepressants and tranquilizers over the years, as well as undergoing counseling and relaxation training all to no benefit. Chiropractic examination revealed areas of upper and mid cervical, upper and mid thoracic and right sacroiliac fixations. The patient's blood pressure would read 182/102 mm Hg and her pulse rate 120 beats per minute during an attack. He blood pressure would drop to 140/80 and her pulse to 76 beats per minute four minutes after the adjustment. She had been free of panic attacks for more than two months which is the best she had been in years in spite of the fact that her M. D. cut her Xanax dosage in half after she began chiropractic car.


Spinal patterns as predictors of personality profiles: a pilot study. Koren T. and Rosenwinkel D. International J of Psychosomatics. 1992; 39: 10-17.
Forty patients were analyzed by full spine (14"x36") radiographs in both sitting (A to P and lateral) a standing (A to P and lateral) positions. Their radiographs were analyzed for distance from center of gravity, pelvic drop, occipital, atlas (C-1), T1, T2 and Sacral angles plus the degree and level of thoracic Kyphosis. Each patient took a Minnesota Multiphasic Personality Inventory (MMPI) test. The authors then analyzed the data from the radiographs and MMPI for any correlations between psychological expression and spinal indicators. Among the findings: atlas angle (the measure of the number of degrees he atlas deviated from the horizontal plane) correlated to three MMPI scales: hypochondriasis, hysteria and paranoia in both standing and sitting films; the degree of the thoracic curve correlated with the hypomania scale (depression and low energy) only in the standing films and the pelvic drop correlated with "need for nurturing" in the sitting films. These findings seemed to agree with Dr. Lowell Ward's Spinal Column Stressology observations. The chief author (Dr. Koren) wishes to expand this pilot study as more research in this area is badly needed.


The chiropractic management of anxiety: a case report. Sullivan EC. ACA J of Chiropractic, 1992 (SEP); 29:29-34.
A 42-year-old female patient suffered from anxiety attacks and agoraphobia since an auto accident. Other symptoms included nightmares, insomnia, tachycardia, dizziness, memory loss, difficult in concentrating, and urinary bladder urgency. She also reported that a well-controlled peptic ulcer had exacerbated after the accident. Chiropractic analysis revealed major vertebral subluxation complex at C5-6, T5-6, and L5-S1 levels. After two months of chiropractic adjusting and counseling patient reported a sharp reduction in anxiety, an end to agoraphobia attacks, bladder urgency, insomnia and dizziness and reduced low back pain. After an additional four months patient reported complete relief from anxiety and ulcer symptoms.


Chiropractic treatment of mental illness: a review of theory and practice. Goff PJ. Research Forum/Autumn, 1987.
From the abstract: Between 1920 and 1960, several residential programs for mental health treatment by chiropractors were in existence. This interest has been largely forgotten in the following years. The size of two Davenport institutions were remarkable, especially considering the varying economic climate during those years and that all payment was by individuals or their families. State-operated facilities were concurrently available at little or no cost. The length of existence of the chiropractic sanitaria, 40 years, is also remarkable, as is their demise at roughly the same time(c. 1960). W.H. Quigley, D.C., claimed successful treatment fo60% of the admitted population, while the state hospitals of that time reported a success rate of 30%.


Chiropractic Success in a Reform School Report of state Supervisor of Chiropractors of Kentucky In Connection With Kentucky Houses of Reform, Greendale, Kentucky, Marshall L.T., Lexington, Kentucky (December 1, 1931).
This little know report documents chiropractic success in a Kentucky Reform School. 244 boys were placed under chiropractic care. The Report is largely made up of cases histories of all the 244 boys many of whom undoubtedly suffered form various emotional and learning disorders. The success of chiropractic care is admirable. From the summary:

  1. Number of boys given chiropractic adjustments 244.
  2. Number of cases dismissed completely recovered or greatly benefited, 155
  3. Of the 244 cases 89 are still under treatment
  4. Number of cases promoted in school grades 54
  5. Number of cases paroled 144
  6. Number of boys at Greendale (Kentucky Houses of Reform) at beginning of chiropractic program (September 3, 1930) approximately 540
  7. Number of boys at Greendale Dec. 1st, 1931 approximately 335


State officials were so impressed that they wrote enthusiastic letters of endorsement. From B.W. Hubbard, Superintendent, Commonwealth of Kentucky. Kentucky Houses of Reform: "I have been able to notice a marked improvement in the mental and physical condition of the boys and in school work and conduct; also, there has been a larger number of paroles during that period than any previous period during the past four years. " (p.3)
"We have been able to accomplish results far beyond their fondest hopes and expectations in the rehabilitation of these boys. The teachers have voluntarily and without solicitation signed a petition asking for a all-time or full-time chiropractic in that institution." (p.1)
From the teachers: "As the records will show the boys who underwent treatment improved from the first adjustment and in many instances showed improvement beyond belief. Not only did they improve in health, but also in their school work as pupils, showing better results in the shops and other industrial training and above all there has been a marked improvement in their moral life." (p.7)
Despite these endorsements, chiropractic services were not continued at the institution. (Copy of this report can be obtained from the Palmer College reference library).


Chiropractic approach to premenstrual syndrome (PMS). Whittier MA Journal of Chiropractic Research and Clinical Investigation, 1992;8:26-29.
Eleven women with histories of PMS had improvement of all measured symptoms including "variation in sexual drive/habits," "social impairment" and depression.


Effects of chiropractic treatment on blood pressure and anxiety. Yates RG, Lamping DL, Abram NL, Wright C. JMPT 1988;11:484-8.
In this patient-blinded, placebo-controlled study the authors state that the data "lend support to the hypothesis that chiropractic manipulation of the thoracic spine significantly reduces blood pressure in patients with elevated blood pressure." Both systolic and diastolic blood pressure decreased significantly in the adjusted group. No significant changes occurred in the placebo or control groups.

Effect of osteopathic medical management on neurologic development in children. Frymann VM, Carney, RE, Springall P. Journal of the American Osteopathic Association, 1992; 92:729-744. (Address reprint requests to : Viola M. Fryman, PO Osteopathic Center for Children, 8030 Girard Avenue, La Jolla, CA 92037-4137.
Author's abstract: For 3 years, children between 18 months and 12 years of age, with and without recognized neuralgic deficits, were studied at the Osteopathic Center for Children. Their response to 6 to 12 osteopathic manipulative treatments directed to all area of impaired inherent physiologic motion was estimated from changes in three sensory and three motor areas of performance. Neurologic performance significantly improved after treatment in children with diagnosed neurogic problems and to a lesser degree in children with medical or structural diagnoses. The advances in neurologic development continued over a several months interval. The results support the use of osteopathic manipulative treatment as part of pediatric health care based on osteopathic medical philosophy and principles.
