Coexistence of hysterical and organic symptoms in two cases of mine explosion.

Cases 116 and 117. (Smyly, April, 1917.)

A soldier was blown up by a mine and rendered unconscious. Upon recovery of consciousness, he was dumb, unable to work, very nervous, paralyzed as to left arm and leg. The paralysis improved so that in the hospital at home the patient became able to get about. However, he threw his legs about in an unusual fashion. Several months later, the patient was much improved.

Shortly, however, there was a relapse. Transferred to a hospital for chronic cases, the patient was unable to walk without assistance on account of complete paralysis of the leg. Insomnia, general tremor, and a bad stuttering developed, with a habit of starting in terror at the slightest noise.

Hypnotic treatment was followed by almost complete disappearance of the tremor. The patient began to sleep six or seven hours a night; nervousness diminished, and the stuttering slowly improved; but neither the paralysis nor the anesthesia of the left leg was affected by suggestion. The leg remained cold, livid, anesthetic, and flaccidly paralyzed to the hip. Though a slight improvement has since been produced by faradization, the patient still can walk only with assistance.

A man was injured in 1906 by the fall of a heavy weight on his back. In 1914 he went to France as a soldier, and eight months later was hurled into a shell hole so that his back struck the edge. He was rendered unconscious. Upon recovery of consciousness, the right leg was found to be swollen, and there were severe pains in the legs and back.

Since return home the patient had gone from one hospital to another, for the most part unable to walk, suffering from agonizing pain in the head and eyes, unable to sleep, and in the night subject to horrible waking dreams.

MINOR SIGNS OF ORGANIC HEMIPLEGIA

(LHERMITTE)

I.	Hyperextension of forearm (hypotonia).
II.	Platysma sign: Contraction absent on paralyzed side.
III.	Babinski’s flexion of thigh on pelvis (spontaneous, upon suddenly throwing seated subject into dorsal decubitus).
IV.	Hoover’s sign: Complementary opposition (on request to raise paralyzed arm, presses opposite arm strongly against mattress).
V.	Heilbronner’s sign of the broad thigh (hypotonia).
VI.	Rossolimo’s sign: flexion of toes on slight percussion of sole.
VII.	Mendel-Bechterew sign: flexion of small toes on percussion with hammer of dorsal surface of cuboid bone.
VIII.	Oppenheim’s sign (extension of great toe on deep friction of calf muscles); or Schaefer, or Gordon (on pinching tendo Achillis).
IX.	Marie-Foix sign: withdrawal of lower leg on transverse pressure of tarsus or forced flexion of toes, even when leg is incapable of voluntary movement.

At first able only to bring himself to an upright position and to rush a few steps, he later acquired considerable control of his feet and legs through crutches. The insomnia persisted.

Smyly regards this case, like Case 116, as more neurological than mental.

Re organic neurology, much of great value has been reported.

Sargent and Holmes say that, contrary to expectation, there have been few war cases of bad sequelae of cerebral injuries, such as insanity and epilepsy. During early stages, after infection of the head wounds, there is dulness and amnesia, irritability and childishness—symptoms which disappear during and after repair of the wounds. Mental disorder requiring internment is surprisingly rare. During 12 months only eight cases were transferred from the head hospital in a year to the Napsbury war hospital, where cases of insanity attributable to the service are sent; and in but two of these could the persisting mental symptoms be attributed to head injury.

Col. F. W. Mott confirms the opinion of Col. Sargent and Col. Holmes, remarking that from all the London County Council Asylums, only one case of insanity associated with gunshot head wound had been admitted, and that this was one of a Belgian who died from septic infection of the cerebral ventricles. Yet all cases of insanity in invalided soldiers belonging to the London County Council area (about one-seventh of the population of the United Kingdom) are transferred to these asylums.

Again Sargent and Holmes point out that both generalized and Jacksonian epileptiform seizures are comparatively rare in patients suffering from recent head wounds; even convulsions in later stages have been as yet less common than was feared. Thus, after evacuation to England, fits occurred in 37 (6 per cent) of 610 cases with complete notes, and in only eleven of these 37 cases were the convulsions frequent. Sargent and Holmes remark, however, that the practice of giving bromides regularly to all serious cranial injuries until the wound is healed, and for some months afterwards, seems advisable. In 33 of the 37 convulsive cases there have been severe compound fractures of the skull, and in four of these a missile was still present in the brain. Five secondary operations were performed with good results, after drainage of small abscesses in two and removal of spicules of bone in three. The In-patient and Out-patient records of the National Hospital for the Paralyzed and Epileptic were searched for epileptics already discharged from the army, but notes of but two patients attending this hospital for epilepsy were found.

As for other neurological complications aside from septic infection and hernia formation, there are a few subjective symptoms that may necessitate the invaliding of soldiers. The most common of these is headache, usually in the form of a feeling of weight, pressure, or throbbing in the head, which headache is increased by noise, fatigue, exertion, or emotion. Attacks of dizziness also occur, and nervousness or deficient control over emotions and feelings. Changes of temperament are found in some soldiers, who become depressed, moody, irritable, or emotional, and unable to concentrate attention.

Foix, under the direction of P. Marie, worked upon aphasia in 100 cases, reporting results at a surgical and neurological meeting, May 24, 1916, in Paris. Only lesions on the left side of the brain have produced important and lasting speech disorder, although lesions on the left side may leave behind them a little dysarthria or difficulty in finding words in conversation. It is, of course, hard to tell speech disorder from stupor or clouding of consciousness. Foix notes certain specialties in speech defect according to which region of the left brain is affected.

First: Prefrontal lesions produce a transient dysarthria, lasting but a few weeks, and right-sided prefrontal lesions produce just as much disorder.

Occipital lesions produce no speech disorder.

Second: Patients with right-sided hemianopsia due to lesions of occipital regions were not aphasic and could read or write perfectly. Lesions of the left visual centers certainly do not affect reading. If, however, the injury is not to the visual centers, but is upon the lateral part of the occipital lobe, then alexic phenomena appear, and these the more the lesion approaches the temporal-parietal region.

Third: Central convolutional lesion produces a variety of disorders according to the site and extent of the lesion. There is no aphasia with the crural monoplegia due to superior paracentral disorder. But slight aphasic disorder accompanies the brachial monoplegia of middle central lesion, though writing, reading, and calculation are slightly affected, and the more so the more the lesion extends posteriorly to the stereognostic regions. The lower down in the precentral region the lesion appears, the more likely is the Broca syndrome to be observed. But if the hemiplegia is chiefly a brachial monoplegia, the aphasic disorder may remain slight, involving reading, writing, understanding of words, the spoken word, articulation, and calculation.

Fourth: Lesions of the lateral-frontal region produce more or less marked aphasic disorder, just as do those of the inferior part of the precentral gyrus. This aphasia is more apt to occur when the wound is deep. However, no case of permanent aphasia has been observed in cases of lesion of the lateral-frontal region (termed in Foix’s nomenclature, the precentral region, but referring to the tissues in front of the precentral (or ascending frontal) gyrus of the more familiar nomenclature). Almost absolute, or absolute, anarthria follows the wound, and the patient is hemiplegic. This hemiplegia may last from ten days to two or three months. After a time there is no longer more than a slight dysarthria, and writing becomes good again; reading remains, perhaps, a little difficult. A complete or almost complete cure is the rule.

Fifth: When the retrocentral region is injured, various aphasic syndromes appear. The retrocentral region is the parietal-temporal lobe except the superior part of the parietal lobe and the anterior part of the temporal lobe, which latter two regions when injured do not allow any marked aphasic disorder. Lesions of the middle or posterior temporal region are particularly important for speech, and produce more marked disorder than lesions of the angular gyrus or the supramarginal gyrus. At first, words cannot be spoken, for a period of a fortnight to three months. Speech returns progressively, with an increased power of comprehension. At the same time, the patients begin to read and write. But there is no further spontaneous progress after a period of six or eight months, and then special reëducation must be started. These speech disorders of retrocentral (parietal-temporal) origin are either aphasic syndromes or slight remains of psychical disorders, or again, a disorder practically limited to alexia. The true aphasic syndromes concern the spoken word, understanding the words, writing, and calculation. The disorder is not especially dysarthric and consists particularly in loss of vocabulary. It might be called an amnestic aphasia (Pitres). These cases have well-marked intellectual disorder and their power of calculation is especially poor. As to the aphasic traces, which are more important to understand than they are extensive in point of fact, they relate particularly to calculating power, to vocabulary (slowness in finding words), and to reading (reading without comprehension). As to the cases of alexia, these are cases of lesions of the posterior part of the parietal-temporal lobe, and are usually accompanied by a hemi- or a quadrantanopsia.

To sum up, cases with central lesions (precentral and postcentral gyrus) have hemiplegia and a Broca aphasia without much tendency to cure. Cases with lesions anterior to the central convolutions have a transient anarthria and their recovery is ordinarily complete. Cases with retrocentral lesions have an aphasia suggestive of Wernicke’s aphasia, and ordinarily leave behind them extensive defects in intelligence and language. These cases should be taken account of from the standpoint of compensation, since they are much worse off for work than many cases with amputations; and though their disorder looks slight, it quite interferes with working at a trade. From the point of view of military effectiveness, the retrocentral cases are not very good soldiers, and especially not good officers, as they do not understand commands completely.
