Description:Brief Description of the Drawings
Generally, the present disclosure relates to health monitoring systems. Particularly, the present disclosure relates to a system for proactive seizure prediction and alerting.
Background
The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
In the realm of medical diagnostics and patient monitoring, a significant challenge remains in the early detection and management of seizure disorders. Seizures, unpredictable in nature, necessitate continuous monitoring to mitigate risks and administer timely intervention. Traditional methods of seizure detection largely depend on the monitoring of physiological signals, primarily through hospital-based systems that require significant resources and specialized equipment.
Furthermore, the advent of wearable technology has seen the development of portable monitoring systems. These systems, equipped with sensors for the acquisition of physiological data, mark a significant advancement in patient-centric healthcare. Among the data acquired, the Electroencephalogram (EEG) is paramount for its direct correlation with brain activity, often utilized alongside other signals such as the Electrocardiogram (ECG), Electromyography (EMG), and Electrooculography (EOG) to enhance diagnostic accuracy.
However, the processing and analysis of such data present inherent challenges. The extraction of meaningful features from raw physiological signals requires sophisticated algorithms capable of identifying potential indicators of seizure activity. Traditional systems often fall short in this regard, lacking the advanced computational techniques necessary for effective feature isolation.
Privacy concerns further complicate the widespread adoption of continuous monitoring systems. The sensitive nature of physiological data mandates stringent measures to ensure patient privacy. Existing systems, while effective to a degree, often lack the necessary mechanisms to provide differential privacy without compromising the integrity of the data.
Moreover, the classification and prediction of seizure events remain a complex task. The variability in seizure manifestations necessitates a highly nuanced approach to detection. Previous systems have employed various methods, but many fail to achieve a balance between sensitivity and specificity, leading to a high rate of false positives or negatives.
Additionally, the confidence in seizure predictions is a crucial factor. Systems that lack a reliable method for evaluating prediction confidence may lead to unnecessary alarm and anxiety among patients and caregivers. The assessment of prediction confidence, thus, remains a key challenge for existing seizure detection systems.
Given the limitations of current methodologies and technologies, there exists an urgent need for solutions that overcome the challenges associated with conventional systems and techniques for the proactive prediction and alerting of seizure events. Such solutions should offer advanced feature extraction, ensure privacy preservation, accurately classify and predict seizure events, and provide reliable confidence evaluation mechanisms to facilitate timely and appropriate response.

By reducing the spatial size of the representation, the system can efficiently process the physiological data, ensuring timely and accurate seizure predictions.
In another embodiment, the system (100) incorporates a confidence evaluation mechanism that utilizes a dynamic threshold adaptive based on historical prediction accuracy. This mechanism assesses the reliability of seizure predictions by adjusting the confidence threshold in response to the system's past performance. Such adaptability ensures that alerts are only issued when the system's predictions surpass a confidence level informed by historical accuracy, minimizing false alarms
In an embodiment, the system (100) further comprises an intervention unit equipped to automatically administer medication upon the triggering of an alert. The intervention unit is integrated into the system (100) to provide a responsive therapeutic intervention following the proactive seizure prediction. Upon the seizure classification and prediction unit's determination that a seizure event is imminent, and when the confidence evaluation mechanism confirms the prediction's reliability exceeds the predetermined confidence threshold, the intervention unit is actuated. Said intervention unit is preloaded with medication specifically prescribed for the patient and is connected to a delivery mechanism. The delivery mechanism is configured to administer the medication in a timely manner, potentially mitigating the effects of the seizure or preventing the seizure altogether. The actuation of said intervention unit is performed in real-time and is synchronized with the alert system to ensure prompt response following the prediction of a seizure event. This aspect of the system (100) emphasizes patient safety by reducing the time between seizure prediction and therapeutic intervention, thereby providing an automated approach to seizure management. The incorporation of said intervention unit into the system (100) ensures that both monitoring and initial treatment steps are addressed within a single integrated solution, enhancing the overall efficacy of the seizure management protocol provided by the system (100).
FIG. 2 illustrates a seizure prediction system that utilizes multiple biosignals for proactive seizure detection, in accordance with the embodiments of the present disclosure. The biosignals include Electroencephalography (EEG), Electrocardiography (ECG), Electromyography (EMG), and Electrooculography (EOG). Each of these signals offers unique insights into physiological states that may precede a seizure. The collected biosignal data are subjected to feature extraction processes that involves distilling the raw biosignal data into meaningful patterns or attributes that can be analyzed effectively. Upon extraction of features, the data proceeds to the seizure classification phase, using secure DeepConvEEGNet algorithm that can distinguish between normal and pre-seizure states. The classification is based on a predictive confidence threshold mechanism, a quantitative measure that determines the likelihood of a seizure event. If the system's confidence that a seizure is forthcoming surpasses a predetermined threshold, an alarm is triggered.
FIG. 3 illustrates architecture of the secure DeepConvEEGNet algorithm, in accordance with the embodiments of the present disclosure. The neural network is designed with privacy-preserving features, using a differential privacy layer to enable that patient data is handled securely. The architecture begins with the raw input EEG data which is then passed through a privacy layer that injects noise, thereby obfuscating patient-specific details and ensuring that the data analysis adheres to privacy standards. Following the privacy layer, the data passes through multiple convolutional layers. Each convolutional layer is characterized by filters and a Rectified Linear Unit (ReLU) activation function, which identifies and activates relevant patterns within the data. The layers also include Batch Normalization (BN), which stabilizes the learning process by normalizing the input layer by adjusting and scaling the activations. Subsequent to the convolutional layers, the architecture employs max-pooling operations, which reduce the dimensionality of the data, condensing the feature set while preserving the most significant features identified by the previous layers. This step enhances the efficiency of the network by reducing computational load and helps in preventing overfitting. The network then channels the data through a dense layer which is connected to a global average pooling function. The dense layer includes a dropout mechanism with a rate of 0.5, a regularization technique used to prevent overfitting by randomly deactivating a portion of the neurons in the layer during the training process. The output layer, which is responsible for the seizure prediction. The output is derived from the processed and analyzed data, culminating in the delivery of a predictive result. This result is utilized by the system to determine whether to activate the real-time alarm.
The system of present disclosure aims to address the challenge of accurately predicting and alerting healthcare providers of impending seizure events while enabling the privacy of patient medical data. The multimodal signal processing which process physiological data from various sources including EEG, ECG, EMG, and EOG for seizure prediction. The diverse data gathered is then refined through a feature extraction process, isolating characteristics that are indicative of potential seizure activity.The system integrates a differential privacy layer early in the data processing stage. A noise injector within this layer introduces a calculated amount of random noise to the data, for masking individual identities while retaining the overall patterns that signal seizure occurrence. Further, dense neural network evaluates the data processed by the Conv2D layers, assigning classifications and forecasting potential seizure events. The inclusion of global average pooling and dropout techniques within this stage mitigates overfitting, improve the model's robustness. The reliability of the predictions is determined by a predictive confidence threshold mechanism. Only when the model's prediction exceeds a predefined confidence level does it trigger an alert, thereby reducing false alarms. Upon high-confidence detection of a possible seizure, the system activates a real-time alert, promptly notifying healthcare providers to initiate preemptive measures.
