“Poor speech may be a precursor to cerebral thrombosis, or it may be caused by other cerebrovascular diseases, intracranial infections, craniocerebral injuries, muscle lesions, etc. It is recommended to consult a doctor for a clear diagnosis in time after the appearance of symptoms. 1. Cerebral thrombosis usually develops in a quiet state, during sleep. When there are symptoms such as unclear speech or language comprehension disorder, numbness or weakness of one side of the limbs, numbness or crookedness of one side of the face, staring with both eyes to the side, blurred or impaired vision, dizziness and vomiting, headache, confusion, convulsions, etc., the possibility of cerebral thrombosis should be considered, and timely checkups and treatments should be carried out. 2. Poor speech can also be seen in other diseases, such as cerebrovascular diseases like cerebral hemorrhage, intracranial infections like meningoencephalitis, demyelinating diseases of the central nervous system like multiple sclerosis, movement disorders like Parkinson’s disease and Huntington’s disease, craniocerebral injuries or tumors that cause damage to the speech center, and muscular disorders such as myasthenia gravis and progressive muscular dystrophy that affect articulation-related muscles. When the manifestation of poor speech occurs, it is important to consult a specialist for a clear diagnosis and prompt treatment.
