In a great majority of the cases the cause lies in the interference
between the fourth dorsal vertebra and the eighth, which analyzed
means a disturbance of the great splanchnic nerves, through whose
interference would be caused the toxic condition and even the sexual
disturbance described in so many cases from standard authorities. The
same lesion, if deep seated enough, could produce an interference with
the vasomotors and reflexly interfere with the circulation to the
brain. In many we also find a first, second or third cervical lesion.
The effects of these lesions on the equilibrium of the circulation to
the brain are easily traced through the superior cervical sympathetic
ganglia. These lesions, namely, the mid-dorsal and upper cervical,
especially when corrected in the earlier stages, have thus far proven
to produce successful results. In a lesser number of cases we find the
cause to be from the first to the fourth dorsal vertebræ; our reasoning
here being that the interference or the physical disturbance must be
so deep that it reaches and interferes with the deeper nerve currents,
both downward and upward, thus disturbing the equilibrium of the
circulation to the brain. We have found this class to be the hardest
to respond to treatment; however, that may be due to the fact that
the physical defects at that point are harder to correct. Osteopathic
treatment applied to the lesions above described without question
offers therapeutics of intrinsic value to this class of patients.
