Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.
It is difficult to tell what type of aphasia your mother has based on the information you provided. To accurately classify, it is important to know the fluency of the spoken language (i.e., is your mom frustrated with speaking or not), comprehension (i.e., does she understand people when spoken to or not), repetition (i.e., can she repeat what words or sentences when asked after having them spoken to her), and writing/reading. There are other components to aphasias, but knowing this information will provide enough information to describe the aphasia.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
