There is no such thing as “10 features of tachyphylaxis in girls”. Different patients with tachyphylaxis will have different clinical manifestations and different features, such as muscle weakness, muscle atrophy, muscle fasciculations, medullary palsy, and so on. Acromegaly belongs to motor neuron disease, which is a neurodegenerative disease characterized by damage to upper and lower motor neurons. Tachyphylaxis in females is mainly caused by damage to the upper and lower motor neurons, and can be manifested by different clinical symptoms, not all of which may occur. The clinical features of tardive dyskinesia in females can be characterized as disseminated, insidious onset after middle age, slow progression, asymmetry, muscle weakness, muscle atrophy, muscle fasciculations, medullary palsy, positive pathological signs, tendon reflex hyperreflexia, etc., and there is no objective sensory impairment, no sphincter dysfunction. When one or more of the above features of acromegaly appear in women, it is recommended that the patient go to the neurology department as soon as possible to improve the relevant auxiliary examinations under the guidance of a professional physician to make a clear diagnosis, so as to avoid delaying the condition.
