There may be concurrent abnormal muscle tone, either hypotonia or rigidity. Hyperpronation of the upper extremity may be seen when attempting to maintain an extended posture. The pathophysiology of chorea (as for ballismus) is unknown; movements may be associated with lesions of the contralateral sub- thalamic nucleus, caudate nucleus, putamen, and thalamus. One model - 72 - Chromesthesia C of basal ganglia function suggests that reduced basal ganglia output to the thalamus disinhibits thalamic relay nuclei leading to increased excitability in thalamocortical pathways which passes to descending motor pathways resulting in involuntary movements. Recognized causes of chorea and choreoathetosis are many, including: ● Hereditary: Huntington’s disease (HD) Dentatorubropallidoluysian atrophy (DRPLA) Neuroacanthocytosis Benign hereditary chorea Paroxysmal dyskinesias: paroxysmal kinesigenic choreoathetosis (PKC) and paroxysmal dystonic choreoathetosis (PDC) ● Sporadic: Drugs: levodopa therapy in later stages of idiopathic Parkinson’s disease Pregnancy: chorea gravidarum Hyperthyroidism Systemic lupus erythematosus (SLE) Sydenham’s chorea (post-infectious, rheumatic chorea, St. Vitus dance, PANDAS) Polycythemia rubra vera (hyperviscosity) AIDS Hyperosmolality (hyperglycemia, hypernatremia) CNS tumor Multiple sclerosis (rare) Variant Creutzfeldt-Jakob disease “Senile chorea” (diagnosis of exclusion, especially of HD) Where treatment is necessary, antidopaminergic agents, such as dopamine receptor antagonists (e. Chronic neuroleptic use may also cause chorea, but these movements are repetitive and predictable, unlike “classic” chorea.

Chvostek’s sign is observed in hypocalcemic states, such as hypoparathyroidism and the respiratory alkalosis associated with hyperventilation. There may be concurrent posturing of the hand, known as main d’accoucheur for its resemblance to the posture adopted for manual delivery of a baby. The pathophysiology of this mechanosensitivity of nerve fibers is uncertain, but is probably related to increased discharges in central pathways. Although hypocalcemia might be expected to impair neuromuscular junction transmission and excitation-contraction coupling (since Ca2+ ions are required for these processes) this does not in fact occur.

Other pathologies include pontine hemorrhage and central pontine myelinolysis. Bilateral ventral midbrain and internal capsule infarcts can produce a similar picture. The locked-in syndrome may be mistaken for abulia, akinetic mutism, coma, and catatonia.

It may be described as the festinating rep- etition of individual phonemes. Logoclonia is an indicator of bilateral brain injury, usually involv- ing subcortical structures, and may be seen in the late stages of demen- tia of Alzheimer type (but not in semantic dementia). Cross References Echolalia; Festination, Festinant gait; Palilalia; Perseveration - 187 - L Logopenia Logopenia Logopenia is a reduced rate of language production, due especially to word finding pauses, but with relatively preserved phrase length and syntactically complete language, seen in aphasic syndromes, such as primary progressive aphasia. Cross References Aphasia Logorrhea Logorrhea is literally a flow of speech, or pressure of speech, denoting an excessive verbal output, an abnormal number of words produced during each utterance. The term may be used of the output in the Wernicke/posterior type of aphasia, or of an output which superficially resembles Wernicke aphasia but in which syntax and morphology are intact, rhythm and articulation are usually normal, and paraphasias and neologisms are few. Moreover comprehension is better than antic- ipated in the Wernicke type of aphasia. Patients may be unaware of their impaired output (anosognosia) due to a failure of self-monitoring. Logorrhea may be observed in subcortical (thalamic) aphasia, usually following recovery from lesions (usually hemorrhage) to the anterolateral nuclei. Similar speech output may be observed in psychi- atric disorders, such as mania and schizophrenia.

Following the standard order of neurological examination of the motor system, the signs include: ● Appearance: muscle wasting; fasciculations (or “fibrillations”) may be observed or induced, particularly if the pathology is at the level of the anterior horn cell - 188 - Lower Motor Neurone (LMN) Syndrome L ● Tone: reduced tone (flaccidity, hypotonus), although this may simply reflect weakness ● Power: weakness, often marked; depending on the precise patholog- ical process, weakness often affects both flexor and extensor muscles equally (although this is not always the case) ● Coordination: depending on the degree of weakness, it may not be possible to comment on the integrity or otherwise of coordination in LMN syndromes; in a pure LMN syndrome coordination will be normal ● Reflexes: depressed (hyporeflexia) or absent (areflexia); plantar responses are flexor. It is often possible to draw a clinical distinction between motor symptoms resulting from lower or upper motor neurone pathology and hence to formulate a differential diagnosis and direct investiga- tions accordingly.
Jarock, 40 years: A basic examination should include measurement of respiratory rate, pulse, and blood pressure; brief assessment of the level of consciousness and pupillary responses; and examination of the head, chest, abdomen, pelvis and limbs for obvious signs of (c) trauma. He had been formed by Nicoladani in 1882, when he attached obliged to rewrite the whole work and to arrange the peronei to the tendo achillis in a patient with the various subjects according to their etiology talipes calcaneus. The classic example, and probably the most frequently observed, is abducens nerve palsy (unilateral or bilateral) in the context of raised intracranial pressure, presumed to result from stretching of the nerve over the ridge of the petrous temporal bone.

These signs should be documented serially to assess any progres- sion of coma.

Prolonged seem to be tolerant of hypoxia and resuscitation should be attempts in such patients are rarely successful and are continued for longer than in adults associated with a high incidence of cerebral damage. Flexion and extension correction was not generally taken into account, and only simple varus correction was performed.
