Appropriate suggestion accompanying the use of a plain glass or two glasses which neutralize each other must be hysterical. Many cases where eye-strain and various nervous disturbances appear to be relieved by very weak glasses or slight change in ocular muscles are similar. Concentric contraction of visual field with reversed color fields is generally proof of hysteria, but significance is doubtful without other signs. Monocular diplopia or polyopia without gross error of refraction is almost certainly hysterical. Intense photophobia without inflammatory condition indicates hysteria.
Neurasthenia involves functional weakness of nervous system, especially higher centers. Uncomplicated case recognized by absence of symptoms characteristic of organic disease, neurotic inheritance, exhausting diseases, injuries, emotional strain, overwork, sexual excesses, toxic conditions and insufficient food. Signs include lack of zest for work, poor concentration, early mental fatigue, morbid sensations in head not amounting to pain but vague feelings like soreness, dizziness, weight, confusion; feelings of distress in spine, heart, stomach; excessive sensitivity to annoyances; irrational fears; inability to divert mind from certain thought or phrase which keeps recurring and may compel patient to resume tiresome performance; impaired vasomotor control, cardiac palpitation, nervous indigestion, sexual debility.
Mixed forms of disease often occur where two or more diseases coexist. Such complications can lead to incomplete diagnosis if symptoms not harmonizing with initial opinion are ignored. Proper diagnosis requires thorough examination and investigation of anomalous symptoms with care. Critical point is decision whether organic disease exists based on symptoms mentioned in tables as indicative.

Hemiplegia involves paralysis of leg, arm and tongue on one side. Occurs at birth with convulsions; in infancy during infectious disease marked by convulsions; after infancy sudden onset often with loss/disturbance of consciousness, sometimes aphasia accompanying right hemiplegia.
<Callout type="warning" title="Severe Cases">Apoplectiform attack in paretic dementia can lead to severe symptoms including rapid temperature rise and paralysis.</Callout>
Hemiplegia may also occur due to cerebrovascular accidents like cerebral embolism, thrombosis, hemorrhage or meningeal hemorrhage. Symptoms vary based on cause but often include sudden onset with convulsions, headache, coma.

Hemiplegia can also result from intracranial infection or irritation leading to meningitis, cerebritis, abscess. Symptoms include headache, fever, vomiting, delirium, stupor, coma.

Hemiplegia can also result from intracranial tumor or cyst leading to headache, optic neuritis, focal cerebral symptoms. Course is usually long and steadily progressive with mental failure toward end.
Key Takeaways
- Recognize neurasthenia through symptoms like poor concentration, early mental fatigue, and excessive sensitivity to annoyances.
- Identify hemiplegia based on paralysis of limbs and face on one side, often accompanied by convulsions or aphasia.
- Diagnose mixed forms of disease carefully, investigating anomalous symptoms with care.
Practical Tips
- Use diagnostic tables for symptoms to compare descriptions until individual disease is reached.
- Recognize critical symptoms like paralysis, spasm or optic neuritis can lead to proper diagnosis.
- Investigate anomalous symptoms carefully to avoid misdiagnosis.
Warnings & Risks
- Failure to investigate anomalous symptoms may result in incomplete diagnosis of mixed forms of disease.
- Apoplectiform attack in paretic dementia can cause severe symptoms including rapid temperature rise and paralysis.
Modern Application
While the diagnostic methods described here are outdated, understanding historical approaches helps modern readers appreciate advancements in neurological diagnostics. Key concepts like neurasthenia and hemiplegia still have relevance today, though they've evolved into more specific diagnoses.
Frequently Asked Questions
Q: What is considered proof of hysteria according to the chapter?
Concentric contraction of the visual field with reversed color fields (red greater than blue or green greater than red) is generally regarded as proof of hysteria.
Q: How can neurasthenia be recognized in an uncomplicated case?
Uncomplicated neurasthenia is recognized by the absence of symptoms characteristic of organic disease, neurotic inheritance, exhausting diseases, injuries, emotional strain, overwork, sexual excesses, toxic conditions and insufficient food.
Q: What are some critical signs to look for in diagnosing hemiplegia?
Critical signs include sudden onset with convulsions, paralysis of leg, arm, tongue on one side, aphasia accompanying right hemiplegia, and symptoms like headache, fever, vomiting, delirium, stupor, coma.
