Understanding the link between schizophrenia and dementia symptoms can be complex, especially when considering the nuances of individual cases. In your relative's situation, several factors are at play, including her hearing impairment, recent stressors, and the emergence of new symptoms.

Firstly, it’s important to differentiate between schizophrenia and dementia. Schizophrenia is a chronic mental health disorder characterized by symptoms such as hallucinations, delusions, disorganized thinking, and impaired functioning. On the other hand, dementia is a general term for a decline in cognitive function severe enough to interfere with daily life, often accompanied by memory loss, changes in mood, and difficulties with communication.

In your relative's case, the onset of auditory hallucinations (hearing sounds or voices that are not present) and paranoid thoughts (believing that someone is monitoring or following her) could suggest a psychotic episode, which is often associated with schizophrenia. However, these symptoms can also arise in the context of severe stress or trauma, particularly when someone is under significant emotional strain, as you mentioned with your recent injury and the need for her to provide constant care.

The presence of hearing loss can complicate matters further. Auditory hallucinations can sometimes be linked to hearing impairment, as the brain attempts to fill in gaps in auditory input. The buzzing sound she experiences could be a form of tinnitus, which is often associated with hearing loss. It’s crucial to consider whether her auditory symptoms are purely psychological or if they are related to her deteriorating hearing condition.

Moreover, the recent changes in her mood—oscillating between laughter and crying—along with forgetfulness and difficulty completing tasks, may indicate cognitive decline. These symptoms can be early signs of dementia, particularly if they are progressive and interfere with her daily functioning. The fact that she is aware of her condition and recognizes that something is wrong is an important aspect to consider, as insight into one’s condition can vary significantly in dementia and schizophrenia.

Given these complexities, it would be advisable for your relative to undergo a comprehensive evaluation by a mental health professional, ideally a psychiatrist or a neurologist. This evaluation should include a thorough medical history, cognitive assessments, and possibly neuroimaging studies (like an MRI or CT scan) to rule out any structural brain changes that could contribute to her symptoms.

In summary, while your relative's symptoms could align with either schizophrenia or early signs of dementia, the interplay of her hearing loss, recent stressors, and mood changes necessitates a careful and thorough assessment. Early intervention is key in both cases, as treatment can significantly improve quality of life and functioning. Encourage her to seek professional help as soon as possible to clarify her diagnosis and explore appropriate treatment options.
