It is a non progressive neuromuscular disorder causing mild to severe disabilities throughout life.This condition is manifested as a group of persisting qualitative motor disorders which appear in young children due to damage to the brain during delivery or due to some pathological conditions in the intrauterine life.The neuroligical problems are multiple but non progressive in nature.Approximately 2 per 100 live birth is having this problem.This disease is having no hereditary tendency.
Causes of cerebral palsy:
1) Injury to the brain during delivery.
2) As a complication of forceps delivery.
3) Lack of oxygen supply to the baby during delivery.
4) Infections during delivery.
Signs and symptoms of cerebral palsy:--
The signs and symptoms may not be similar in all babies affected.Depending upon the damage to the brain there may be mild to severe lesions.
Mild cases:- 20% children will have mild disability.
Moderate cases:-50% cases are having moderate disability.The affected children require self help for assisting their impaired ambulation capacity.
Severe cases:-About 30% of the affected children are totally incapacited and bedridden and they allways need care from others.
Abnormal findings in cerebral palsy:-
1,Abnormal neonatal reflexes.
2,Stiffness of all muscles with awkward motion.
3,Extention of extremities on vertical suspension of the infant.
4,Scissoring of the lower limbs due to spasm of the adductor muscles of the thigh.
5,In severe cases the back bend backwards like and arch.
6,May have total or partial paralysis.
7,Arrest of neurological and behavioral developement.
8,Swallowing may be difficult in some cases.
9,Drooling of saliva.
10,Mild to severe mental retardations.
11,Abnormal movements are seen in some cases.
12,Tremors with typical movements.
13,If cerebellum is affected there will be loss of muscle tone with difficulty in walking.
14,Complete or partial loss of hearing.
15,Speech may be affected.
16,Squint and other visual problems may be associated.
17,Convulsions may be seen in some children.
Cerebral palsy is diagnosed by detailed clinical examination and by eliminating other similar diseases like brain tumour, progressive atrophy ect.All investigations like CT scan,MRI and routine investigations are needed to ruleout other diseases.
Management of carebral palsy:--
This includes proper nutrition and personal care. Symptomatic medicines are needed to reduce convulsions and muscle stiffness. Diazepam can reduce spasticity and athetosis.
Dantrolene sodium helps to relax skeletal muscles.
Here massage,exercise, hydrotherapy and ect are needed.Special training is given to train walking,swallowing and talking.The affected children are also trained to hold articles for routine activities.
Moral and social support should be given to these children.They should be send to special schools where special training can be given by trained staff.Mentally retarded children need special training.Depending up on the disabitity special instruments and machines are given for locomotion and to assist their daytoday activities.
This is given by occupational therapists.They train the disabled people to do some suitable works so that these people can have their own income.
HOW ALCOHOL AFFECTS THE BRAIN.
I once had the unusual, though unhappy, opportunity of observing the same phenomenon in the brain structure of a man, who, in a paroxysm of alcoholic excitement, decapitated himself under the wheel of a railway carriage, and whose brain was instantaneously evolved from the skull by the crash. The brain itself, entire, was before me within three minutes after the death. It exhaled the odor of spirit most distinctly, and its membranes and minute structures were vascular in the extreme. It looked as if it had been recently injected with vermilion. The white matter of the cerebrum, studded with red points, could scarcely be distinguished, when it was incised, by its natural whiteness; and the pia-mater, or internal vascular membrane covering the brain, resembled a delicate web of coagulated red blood, so tensely were its fine vessels engorged.
I should add that this condition extended through both the larger and the smaller brain, the cerebrum and cerebellum, but was not so marked in the medulla or commencing portion of the spinal cord.
The spinal cord and nerves.
The action of alcohol continued beyond the first stage, the function of the spinal cord is influenced. Through this part of the nervous system we are accustomed, in health, to perform automatic acts of a mechanical kind, which proceed systematically even when we are thinking or speaking on other subjects. Thus a skilled workman will continue his mechanical work perfectly, while his mind is bent on some other subject; and thus we all perform various acts in a purely automatic way, without calling in the aid of the higher centres, except something more than ordinary occurs to demand their service, upon which we think before we perform. Under alcohol, as the spinal centres become influenced, these pure automatic acts cease to be correctly carried on. That the hand may reach any object, or the foot be correctly planted, the higher intellectual centre must be invoked to make the proceeding secure. There follows quickly upon this a deficient power of co-ordination of muscular movement. The nervous control of certain of the muscles is lost, and the nervous stimulus is more or less enfeebled. The muscles of the lower lip in the human subject usually fail first of all, then the muscles of the lower limbs, and it is worthy of remark that the extensor muscles give way earlier than the flexors. The muscles themselves, by this time, are also failing in power; they respond more feebly than is natural to the nervous stimulus; they, too, are coming under the depressing influence of the paralyzing agent, their structure is temporarily deranged, and their contractile power reduced.
This modification of the animal functions under alcohol, marks the second degree of its action. In young subjects, there is now, usually, vomiting with faintness, followed by gradual relief from the burden of the poison.
Effect on the brain centres.
The alcoholic spirit carried yet a further degree, the cerebral or brain centres become influenced; they are reduced in power, and the controlling influences of will and of judgment are lost. As these centres are unbalanced and thrown into chaos, the rational part of the nature of the man gives way before the emotional, passional or organic part. The reason is now off duty, or is fooling with duty, and all the mere animal instincts and sentiments are laid atrociously bare. The coward shows up more craven, the braggart more boastful, the cruel more merciless, the untruthful more false, the carnal more degraded. ' In vino veritas ' expresses, even, indeed, to physiological accuracy, the true condition. The reason, the emotions, the instincts, are all in a state of carnival, and in chaotic feebleness.
Finally, the action of the alcohol still extending, the superior brain centres are overpowered; the senses are beclouded, the voluntary muscular prostration is perfected, sensibility is lost, and the body lies a mere log, dead by all but one-fourth, on which alone its life hangs. The heart still remains true to its duty, and while it just lives it feeds the breathing power. And so the circulation and the respiration, in the otherwise inert mass, keeps the mass within the bare domain of life until the poison begins to pass away and the nervous centres to revive again. It is happy for the inebriate that, as a rule, the brain fails so long before the heart that he has neither the power nor the sense to continue his process of destruction up to the act of death of his circulation. Therefore he lives to die another day.
