Menstrual psychosis with onset after childbirth

Excerpt

After the birth of the last, [she developed] an unusual degree of mental excitement. She talked in a loud voice, and in a more vehement manner than was natural to her. She was highly excited by every trifling circumstance, and even by imaginary causes. She was with difficulty restrained without absolute coercion. Her sleep was disturbed, and she had scarcely any intervals of tranquillity. These symptoms abated as she recovered strength, but recurred in a greater or lesser degree about the periods of the catamenia, at which times she displayed symptoms of mental alienation. She was gradually restored nearly to her usual degree of tranquillity, though still subject to returns of excitement at the periods of the catamenia.
