Glossary
Imperative idea: An idea that, however malapropos it may be, keeps mounting into consciousness.
Obsession: An imperative idea that compels appropriate action.
Phobias: Unconscious fears, often acquired in early infancy, which may ruin a man’s whole life for him. There are many different kinds of “phobia” of which syphilophobia is probably the most common.

Psychasthenia: A weird half-sister of neurasthenia, generally the result of heredity, combined with abnormal education in early youth. In the psychasthenic state the patient may be subject to all manner of imperative ideas, obsessions and phobias. Sometimes he stammers, sometimes he is compelled by his “unconscious”to jerk his limbs about in quaint antics; sometimes he is afflicted with awful doubts and scruples.[1]
All the other medical terms are, I think, explained in the text as they arise.
