التكنولوجيا تغزو الأعصاب..زراعة الشرائح الدماغية و مخاطرها

لم يعد الذكاء الاصطناعي مجرد أداة تساعد الأطباء في التشخيص والعلاج، بل بات يمتد إلى أدمغتنا نفسها، فاتحًا الباب أمام إمكانيات غير مسبوقة، وأيضًا مخاوف وتساؤلات لا حصر لها. يعمل العلماء على تطوير شرائح تزرع داخل الدماغ، قادرة على إعادة الحركة لمرضى الشلل، وتحسين حالات الاكتئاب والقلق، بل وحتى استعادة الذاكرة لمن يعانون من أمراض مثل الزهايمر. فهل نحن على أعتاب ثورة طبية تعيد تشكيل قدراتنا العقلية؟ أم أن هذه التكنولوجيا قد تحمل مخاطر أكبر مما نتخيل؟

تكنولوجيا الشرائح الدماغية لا تزال في مراحلها الأولى عالميًا، وفي مصر بدأ الأطباء في متابعة أحدث التطورات العالمية في زراعة الشرائح الدماغية على أمل توفيرها لمرضى فقدان الحركة أو الاضطرابات النفسية.

“الشرائح الدماغية: أمل للمرضى”

قالت دكتورة ماريا ألفي، أخصائية أمراض مخ وأعصاب بالقصر العيني: “هذه الشرائح تُستخدم في علاج أمراض مثل الشلل، والشلل الرعاش، وبعض أمراض الذاكرة، والأمراض النفسية، والتشنجات، ويتم تطويرها لاستعادة الوظائف الحسية والحركية. ولكن حتى الآن، لن تصل هذه التكنولوجيا إلى مصر لأنها مازالت تحت التجارب والدراسات في الخارج”.

وأوضحت دكتورة ماريا ألفي أن هذه الشرائح تعمل على تسجيل الإشارات العصبية من الدماغ وتحويلها إلى أوامر للأجهزة المستخدمة مثل الأطراف الصناعية، فيتحكم بها المريض من خلال أفكاره. وأضافت أن هناك تجارب حاليًا لتحويل الإشارات العصبية المرتبطة بالكلام إلى نصوص أو أصوات، مما يعطي أملًا كبيرًا لمرضى فقدان النطق.

التحديات والمخاطر

قال الدكتور بولا جرجس، جراح مخ وأعصاب ونائب رئيس جراحة المخ والأعصاب بالقصر العيني سابقًا: “هناك تحديات تقنية وطبية تجعل هذه التكنولوجيا غير بديلة للعلاجات التقليدية في الوقت الحالي، لكنها يمكن أن تقلل من الحاجة للأدوية في بعض الحالات”.

وأوضح د. بولا جرجس أن لهذه الشرائح مضاعفات ومخاطر، من بينها تليف الأنسجة المحيطة بالشريحة، والنزيف الدماغي أثناء الجراحة أو بعدها، والعدوى التي قد تؤدي إلى إزالة الشريحة مع احتمالية حدوث اضطراب في كهرباء المخ. بالإضافة إلى أن هذه الشرائح قد تؤثر على المزاج والسلوك وتحدث تغيرات في التفكير والعاطفة.

مستقبل الشرائح الدماغية في مصر

أضاف د. بولا جرجس أن هناك مستشفيات متقدمة جدًا في مصر مثل القصر العيني، ومستشفى عين شمس التخصصي، ومعهد ناصر، قادرة على إجراء هذه العمليات بمجرد الانتهاء من مراحل البحث العالمية ووصول هذه التقنيات والأبحاث إلى مصر. وأوضح أن عمليات التحفيز العميق تُجرى في مصر لمرضى اضطرابات الحركة ومرضى باركنسون، لكن الشرائح لم تُستخدم حتى الآن.

واختتمت د. ماريا حديثها بقولها: “من المتوقع في المستقبل أن تصبح هذه الشرائح أكثر كفاءة، ويتم التحكم فيها لاسلكيًا، مما سيسمح للمرضى باستخدامها بسهولة أكبر. ودمجها بالذكاء الاصطناعي سيساعد في تفاعلها مع الإشارات العصبية، مما يجعلها أكثر دقة وفعالية”.

لا شك أن الشرائح الدماغية تمثل قفزة هائلة في عالم الطب العصبي، وقد تحمل مستقبلاً مشرقًا لملايين المرضى حول العالم. ومع ذلك، فإن التحديات التقنية والطبية لا تزال قائمة، مما يجعل هذه التكنولوجيا بحاجة إلى مزيد من الأبحاث قبل أن تصبح متاحة على نطاق واسع.
