They feel, and they know, that the mind is deteriorating rapidly. They make mistakes in spelling, and misplacing words while talking or writing. They will use the wrong words; in short they are confused. The speech of Crotalus tends to be some- what clumsy. The patient stumbles over his own words, he mumbles and mutters, makes slips of the tongue, and in more advanced cases forgets what he wanted to say, loses his train of thought, makes mistakes using different words to those intended, and behaves as if intoxicated.
They find it especially difficult to express their emotions, or rather, to find the right words to express them. They know how they feel, but cannot find the words to describe it; it may take some seconds before they find the right word. In this condition they want very little contact with others and appear to be misanthropic. They do not like to talk to others, but may be heard to talk to themselves.
Their thinking process is disconnected, they cannot hold a train of thought for long, the mind wanders and cannot stay with an idea. Clarke gives an expressive picture of this condition: ‘Inability to hold her mind to a subject; perception clouded, on walking in the street would have been run over but for her sister’s watchfulness; entering a shop she forgot what she came to purchase’.
As mentioned above, Crotalus will often finish a cure that Lachesis has begun. It will be useful in differential diagnosis to compare symptoms that are shared between Lach. and Crotalus, though in different degrees:
• ‘Tight clothing aggravates’: around the neck is more intolerable for Lachesis; For Crotalus the aggravation is more when the pressure is on the abdomen, especially the epigastric region.
• Jealousy; ‘worse before menses’; aggravated during sleep:
stronger in Lachesis, less in Crotalus.
