The most well documented account of dysprosody was in 1943 by G. H. Monrad-Krohn. A woman, Astrid L., in Norway was hit with a shell fragment during an air raid in 1941 through her left frontal bone, leaving her brain exposed. She was unconscious for four days and when she regained consciousness at the hospital, she was hemiplegic on her right side, was suffering from seizures, and was aphasic. Initially she could only speak in monosyllables, yes and no, but then started to form sentences. When first starting to speak again, she also spoke with uncharacteristic grammatical errors, but over time they became much less pronounced and eventually she gained back full fluency of speech. However, she sounded as though she was speaking her native Norwegian with a German accent. It was two years later that she was admitted to the Neurological University Clinic in Oslo, Norway and seen by Dr. Monrad-Krohn. Krohn examined the patient and noted that there was no noticeable difference in her fluency, motor functions, sensory functions, or coordination. Upon examination of her skull, he found a large scar on the left fronto-temporo-parietal region. This was not as helpful as Krohn would have liked. Since the scar was so extensive, it was impossible for Krohn to pinpoint the exact region of the brain which was causing this altered speech. Krohn then ran tests on Astrid to assess her language comprehension. He found that in addition to her altered speech patterns, she had trouble finding the Norwegian words for trivial objects, such as light switch and match box. She also had to repeat the examiner's questions aloud before answering, had to say words out loud to herself before writing them down, and had difficulty comprehending written instructions. Krohn could not understand how she had acquired a foreign accent; it could not be attributed to any known disorder or condition. For those who suffer from this type of dysprosody, sometimes the accents they speak are from countries to which the person has never been. This is very puzzling for neuroscientists, since dialects and accents are considered to be an acquired behavior of learning pitches, intonations and stress patterns.
