CHAPTER III. The Differences of the Epilepsie, and the reasons of some of the Symptoms are unfolded. Also its Curatory Method is represented.
THus far of the essence, and the Causes in generall of the Epilepsie, it shall be now our next task, to explicate the differences of this Disease, also the rea∣sons of some of the accidents, and Symptoms, belonging to it: to which we will lastly add, Observations and Histories of sick people, with the method of Curing.
The most notable difference of the Epilepsie, is wont to be taken from the Sub∣ject, to wit, that the brain, or part of it, labouring with this disease, is either primarily, and Idiopathetically, or properly, affected, or secondarily, and not but by consent, with other parts: concerning the former kinde, we have hither∣to discoursed, as to the other, to wit, in which the falling down seems to arise, from some place without the head, and then lays hold of it secondarily, and as it were by a blast sent from elsewhere; It is to be observ'd, that this kinde of di∣stemper (as Galen hath noted) proceeds either from the external, or internal parts: we meet with many examples of Epilepticks, in whom the fit being just coming upon them, a spasm is felt, with a numness in the hand or toe, or other particular member, which presently from thence, as it were with a pricking of tingling, creeps towards the head, which when it hath attained, immediately the sick party falls flat on the Earth, and is hurried into Insensibility and disorder of spirits, and other proper demonstrations of the Symptom of the falling sick∣ness: neither is it a less usuall proaemium of this disease, that there first arises as it were a conflict, in the stomach, spleen, womb, Intestines, genitalls, or other inwards; or that some kinde of perturbation is raised in some of them; then from that place, the ascent of (as it were) a cold air is perceived, to which distem∣per, follows the accession of the falling evill, with its most horrid provision of symptoms: hence it was commonly believed, that the cause of the Epilepsie, lay hid in the part, seen to be so primarily affected, and propagated its evil to the brain, of its self innocent.
But in very deed, as to this, we must say, that in every Epilepsie, not only the procatartick or remoter Cause, but also the conjunct, remains wholly in the Brain; to wit, that the spirits inhabiting it, being disposed to explosions, and there being explosed, bring on or Cause every falling Evill. As to those praeli∣minary Symptoms in some Epileptical people, they sometimes have the place of an Evident Cause, and sometimes only of a signe: For when the evill disposition of any inward, as the stomach, spleen, or womb, happens with the disposition of the Epilepsie, as often as any perturbation is begun in that distempered In∣ward, it easily happens, by reason of a transmission of the ferment from thence, or a continuation of the spasm to the head, an Epileptical fit is excited in the Brain prae-disposed to act.
But these kind of symtoms of the falling evil, which being suscitated from without, seem to propagate the distemper to the Brain, do often arise from the consent of the Brain it self, and are only signs of the approach of the Epileptical Fit, or of the spi∣rits beginning to be exploded, in the brain: For when the animal spirits planted in the middle parts of the Brain, and Cerebel, and also those in the oblong pith or marrow, neer the beginnings of the Nerves, are so filled with an heterogeneous Copula, that, for the Casting of it off, they are ready to bring on the assault of the Disease, before they are all exploded heap by heap, some spirits lying more outward, in some private Nerves, because they are destitute of the wonted in∣flux of their superiors, fall into certain inordinations, and so begin spasms, which spasms (as it is often the manner in this kinde of distemper) begin at the extre∣mities or ends of the Nerves, inserted to this or that member, or Inward, from whence by degrees, they creep forward to their beginnings; whether being come forth with the spirits, thorow the whole Encephalon, before disposed to explosions,
