Yes, disturbed alpha EEG activity could contribute to baseline stress in individuals with schizophrenia. Here’s how this relationship may manifest:

1. **Altered Brain Functioning**: Individuals with schizophrenia often exhibit abnormalities in brain wave patterns, including reduced alpha wave activity. This alteration can affect the brain's ability to regulate stress responses and emotional processing, potentially leading to a heightened baseline level of stress.

2. **Cognitive and Emotional Regulation**: Alpha waves are associated with relaxation and calmness. Disturbed alpha activity may impair an individual's ability to manage stress and anxiety effectively. This can result in a constant state of heightened arousal or stress, making it difficult for individuals to cope with everyday challenges.

3. **Sensory Processing**: Abnormal alpha activity can also affect sensory processing and attention. Individuals with schizophrenia may have difficulty filtering out irrelevant stimuli, leading to sensory overload and increased stress levels in social or environmental situations.

4. **Negative Symptoms**: The negative symptoms of schizophrenia, such as social withdrawal and lack of motivation, can be exacerbated by disturbed alpha activity. This can create a cycle where individuals feel more stressed and overwhelmed, further impacting their ability to engage socially and manage their symptoms.

5. **Anxiety and Paranoia**: Disturbed alpha activity may be linked to increased anxiety and paranoia, common in schizophrenia. These symptoms can contribute to a persistent feeling of stress, affecting overall well-being.

In summary, disturbed alpha EEG activity can play a role in the baseline stress experienced by individuals with schizophrenia, influencing cognitive, emotional, and sensory processing functions. Addressing these disturbances through therapeutic interventions may help in managing stress and improving overall functioning.

In schizophrenia, alpha EEG activity is often both functionally disturbed and decreased. Here’s a breakdown of these aspects:

1. **Decreased Alpha Activity**: Many studies have reported a reduction in alpha wave activity in individuals with schizophrenia compared to healthy controls. This decrease can be observed during resting states and cognitive tasks, indicating a general impairment in the brain's ability to generate alpha waves.

2. **Functional Disturbances**: Beyond just a decrease in alpha activity, there are functional disturbances in how alpha waves are generated and synchronized. For example:
   - **Dysregulation**: Individuals with schizophrenia may exhibit dysregulation in the timing and synchronization of alpha waves across different brain regions. This can affect cognitive processes such as attention, working memory, and sensory processing.
   - **Task-Related Changes**: During cognitive tasks, individuals with schizophrenia may show abnormal patterns of alpha activity, such as insufficient alpha suppression when required to focus or engage in tasks. This can lead to difficulties in maintaining attention and processing information effectively.

3. **Impact on Cognitive and Emotional Functioning**: The combination of decreased and functionally disturbed alpha activity can contribute to the cognitive deficits and emotional dysregulation commonly seen in schizophrenia. For instance, impaired alpha activity may hinder the ability to filter out irrelevant stimuli, leading to sensory overload and increased anxiety.

In summary, alpha EEG in schizophrenia is characterized by both decreased activity and functional disturbances, which together contribute to the cognitive and emotional challenges faced by individuals with the disorder.
