Facts & Symptoms Of Cerebral Palsy

Symptoms & Sign Of Cerebral Palsy

 The predominant symptoms and signs of cerebral palsy are related to motor difficulties, which are the consequence of the brain damage. The extension and severity of the brain lesion is the leading factor in the magnitude of the motor deficit. Many of the symptoms observed in these children are related to the primary problem that is impaired motor functions. For example, developmental motor delay, gait disorders, poor fine and gross motor coordination, swallowing disorders, or speech delay are all the result of the basic motor disorder. The way they present varies from child to child. For that reason, it is difficult to describe a clinical picture that will satisfy every child with cerebral palsy. The clinical presentation, even though with many common features, is very much unique for a particular child. In addition, the comorbid conditions add more to the uniqueness of the presentation of the child with cerebral palsy. For example some children may be blind, while others may have normal vision; or some children may have severe cognitive delay while others may have normal or near normal cognitive level...

Cerebral Palsy Facts

  • Cerebral palsy (CP) is an abnormality of motor function, the ability to move and control movements.
  • Cerebral palsy is acquired at an early age, usually less than a year of age.
  • Cerebral palsy is due to a brain abnormality that does not progress in severity.
  • The causes of cerebral palsy include prematurity, genetic disorders, strokes, and infection of the brain.
  • Taking certain precautions during the pregnancy might decrease the risk of cerebral palsy.
  • Asphyxia, the lack of oxygen to the brain, at birth is not as common a cause of cerebral palsy as had been thought.
  • There are different types of cerebral palsy based on symptoms -- spastic, hypotonic, choreoathetoid, and mixed types.
  • The best approach for diagnosis, treatment, and management is through and interdisciplinary team.
  • Cerebral palsy may be associated with many other medical conditions, including mental retardation or seizures. Many of these conditions can be treated with improved quality of life.
  • Many children with cerebral palsy have a normal intellect and have no seizures.
  • Treatment of cerebral palsy is for the symptoms only; there are few treatments for the underlying causes.
  • There are many alternative medicines promoted for the treatment of cerebral palsy that have never been proven to be helpful. Families and advocates of persons with cerebral palsy should be aware of the lack of scientific basis for these treatments.

Cerebral Palsy And Causes

Hii
Today I am Posting Medical Related Information. I m Talking About CEREBRAL PALSY(CP) Disease In Medical Science There Are thousands And Accurate Treatments Available For Various Disease & Disorders But Why CP has No accurate Treatment option ALL OVER IN WORLD !
So Today Let's Explore The Basics About CP N how can We Prevent CP + Corrective Treatments For CP

What is cerebral palsy?


Cerebral palsy (CP) is an abnormality of motor function (as opposed to mental function) and postural tone that is acquired at an early age, even before birth. Signs and symptoms of cerebral palsy usually show in the first year of life.
This abnormality in the motor system is the result of brain lesions that are nonprogressive. The motor system of the body provides the ability to move and control movements. A brain lesion is any abnormality of brain structure or function. "Nonprogressive" means that the lesion does not produce ongoing degeneration of the brain. It is also implies that the brain lesion is the result of a one-time brain injury, that will not occur again. Whatever the brain damage that occurred at the time of the injury is the extent of damage for the rest of the child's life.
Cerebral palsy affects approximately one to three out of every thousand children born. However, it is much higher in infants born with very low weight and in premature infants.
Interestingly, new treatment methods that resulted in an increased survival rate of low-birth weight and premature infants actually resulted in an overall increase in the number of children with cerebral palsy. The new technologies, however, did not change the rate of cerebral palsy in children born full term and with normal weight.

What are causes of cerebral palsy?


The term cerebral palsy does not indicate the cause or prognosis of the child with cerebral palsy. There are many possible causes of cerebral palsy.
In full-term infants the cause of cerebral palsy is usually prenatal and not related to events at time of delivery; in most instances it is related to events that happened during the pregnancy while the fetus is developing inside the mother's womb.
Premature birth is a risk factor for cerebral palsy. The premature brain is at a high risk of bleeding, and when severe enough, it can result in cerebral palsy. Children that are born prematurely can also develop serious respiratory distress due to immature and poorly developed lungs. This can lead to periods of decreased oxygen delivered to the brain that might result in cerebral palsy. A poorly understood brain process observed in some premature infants is called periventricular leukomalacia. This is a disorder in which holes form in the white matter of the premature infant's brain. The white matter is necessary for the normal processing of signals that are transmitted throughout the brain, and from the brain to the rest of the body.
White matter abnormalities are observed in many cases of cerebral palsy. Nevertheless, it is important to recognize that the vast majority of premature infants, even those born very prematurely, do not suffer from cerebral palsy. There have been many advances in the field of neonatology (the care and study of problems affecting newborn infants) that have enhanced the survival of very premature infants.
Other important causes of cerebral palsy include accidents of brain development, genetic disorders, stroke due to abnormal blood vessels or blood clots, or infections of the brain.
Even though it is widely believed that the most common cause of cerebral palsy is a lack of oxygen to the brain during delivery (birth asphyxia), it is actually a very rare cause of cerebral palsy. When cerebral palsy is the result of birth asphyxia, the infant almost always suffers severe neonatal encephalopathy with symptoms during the first few days of life. These symptoms include:
  • seizures,
  • irritability,
  • jitteriness,
  • feeding and respiratory problems,
  • lethargy, and
  • coma depending on the severity.
In rare instances, obstetrical accidents during particularly difficult deliveries can cause brain damage and result in cerebral palsy. Conversely, it is very unlikely that cerebral palsy symptoms would develop after a few years of age as a result of obstetrical complications.
Child abuse during infancy can cause significant brain damage which, in turn, can lead to cerebral palsy. This abuse often takes the form of severe shaking from a frustrated parent or caregiver, causing hemorrhage in or just outside the brain. To further compound the problem, many children with developmental abnormalities are at risk for being abused. Thus, a child with cerebral palsy may be made significantly worse or even killed by a single incident of abuse.
Despite the diversity of causes of cerebral palsy, many cases remain without a defined cause. However, the enhanced ability to see the brain structure with magnetic resonance imaging (MRI) and CT scans as well as improved diagnostic capabilities for genetic disorders has made the number of such cases much lower.

Windows History

Welcome !
Today Let's Explore The History of Windows. Only Few Engineers or Peoples Know the History of Windows...

A History of Windows

Don’t be surprised if I say that 9 out of 10 computers run some version of the Windows operating system, today. However, no one could have predicted this outcome when the whole journey started with MS-DOS and a vision to have every computer on a desktop. Below, you will find a chronology of events that take you through highlights from the first 25 years of Windows, more preferably – A History of Windows.

Windows Founders 400x276 A History of Windows   Timeline

History of Windows

MS-DOS

It was originally developed by Microsoft for  IBM-compatible personal computers. Although the first version of OS from Microsoft, MS-DOS was little-used or preferred alternative to Apple’s Macintosh. Despite witnessing little success, Microsoft continued to offer support for MS-DOS till the development of Windows XP.

MS DOS A History of Windows   Timeline

 Ever wondered, what MS-DOS stood for?

Microsoft Disk Operating System

Windows 1.0 – 2.0 (1985-1992)

Instead of typing MS-DOS commands, Windows 1.0 allowed users to point and click to access the windows.

In 1987 Microsoft released Windows 2.0, which was designed for the designed for the Intel 286 processor. This version added desktop icons, keyboard shortcuts and improved graphics support.

 Why was Windows OS named so?

Microsoft Windows 1.0 was named so since the computing boxes, or Windows  design represented a fundamental aspect of the operating system.

Windows 3.0 – 3.1 (1990–1994)

Microsoft released Windows 3.0 in May, 1900 offering better icons, performance and advanced graphics with 16 colors designed for Intel 386 processors. Its popularity grew by manifolds following the release of SDK that helped software developers focus more on writing and less on writing device drivers. With Windows 3.0 Microsoft completely rewrote the application development environment. The OS included Program Manager, File Manager and Print Manager and games, remember Solitare, a complete time waster??

What does SDK stands for?

SDK refers to a set of tools that allows for the creation of applications for certain software.

Windows 95 (August 1995)

A major release of the Microsoft Windows operating system that caused Apple’s Market share to decline or shrink was Windows 95. Windows 95 as the name suggests was released in 1995 represented a significant advance over its precursor, Windows 3.1. By the way, this was also the time when the first version of Microsoft’s proprietary browser – Internet Explorer 1 was rolled out in August 1995 to catch up the Internet wave.

Windows 95 400x254 A History of Windows   Timeline

Windows 98 (June 1998)

Described as an operating system that “Works Better & Plays Better, ‘Windows 98’ offered support for a number of new technologies, including FAT32, AGP, MMX, USB, DVD, and ACPI. Also, it was the first OS to include a tool called Windows Update. The tool alerted the customers when software updates became available for their computers.

Which was the last version based on MS-DOS application?

Windows 98 indeed, was the last version based on MS?DOS.

Windows ME – Millennium Edition (September 2000)

The Windows Millennium Edition, referrd as “Windows Me” was an update to the Windows 98 core that included some features of the Windows 2000 operating system. The version had the “boot in DOS” option removed but included other enhancements like Windows Media player and Movie Maker for basic video editing.

 System Restore, a feature that rolled your PC software configuration back to to a date or time before a problem occurred first appeared in which version of Windows?

Windows ME – Millennium Edition

Windows NT 3.1 – 4.0 (1993-1996)

A version of the Windows OS with 32-bit supported for preemptive multitasking. Two versions of Windows NT:

  1. Windows NT Server – Designed to act as a server in networks
  2. Windows NT – Workstation for stand-alone or client workstations

Windows 2000 (February 2000)

W2K (abbreviated form) was an operating system for business desktop and laptop systems to run software applications, connect to Internet and intranet sites, and access files, printers, and network resources. Windows 2000 4 versions released by Microsoft

  1.  Professional (for business desktop and laptop systems)
  2.  Server (both a Web server and an office server)
  3.  Advanced Server (for line-of-business applications)
  4.  Datacenter Server (for high-traffic computer networks)

Windows XP (October 2001)

This version of the OS was built on Windows 2000 Kernel and was introduced in 2001 along with a redesigned look and feel. It was made available to public in 2 versions

  1. Windows Xp Home
  2. Windows XP Professional

Microsoft focused on mobility for both editions, including plug and play features for connecting to wireless networks was introduced in this version of Windows and it proved to one of Microsoft’s best-selling products. Its use started declining with more Windows 7 deployments.

Windows Vista (November 2006)

A marketing flop! People expected too much from its WOW factor. Windows Vista released in November 2006 was widely criticized for performance related issues.

Windows 7 (October, 2009)

Windows 7 made its official debut on October 22, 2009. The OS included enhancements in the form of fast start-up time, Aero Snap, Aero Shake, support for virtual hard disks, a new and improved Windows Media Center, and better security features.

Windows 8

Bill Gates’ vision of the future computing was Touch and voice replacing mouse and keyboard. We already have the touch with Windows 8, a completely redesigned OS built from the ground up.

Thanks for taking us down the memory lane. I remember using WIndows 1 to be installed with 1 5.5″ Floppy drive.

 

I’m 57, and date — computer industry-wise, at least — back to the desktop PC industry as it existed back in the 1970s… which means CP/M, then Apple I and II; then the IBM PC and PC-DOS, then Microsoft’s MS-DOS…

…and somewhere in there I screwed around a bit in the mini- and mainframe computer world, too. So I definitely remember LOOOONNNNGGG before Windows; as well as every single moment of Windows, since. Every single one!

So I can say, with authority, that there is one error, and one slight leaving-out of something in this otherwise excellent piece!

First, the leaving-out: Remember that there were actually two versions of Win98, the second being SE. And, technically, there was kinda’ the same thing with Win95, but it was just less official.

Second, the error: Windows 98 was *NOT* the last FAT-32, MS-DOS-based version. Windows ME was. Windows ME was nothing more than Windows 98, but with Windows 2000-like graphics and icons. Of course that’s an oversimplification, but it pretty much captures the essence of it. ME was entirely based on the 98 kernel. It was the last version of Windows before all versions became NTFS-based.

It’s confusing, I know, because Microsoft, from the outset of Windows 9x, tried, in how talk about Windows in a way that blurred the line between Windows and DOS, calling Windows an “operating system,” when, in fact, all versions of Windows prior to NTFS-based NT — including ME — were nothing more than graphical user interfaces sitting atop FAT-based MS-DOS… and no amount of Microsoft’s wishing, either then or now, changes that. What made it a little more confusing in ME’s case was how MS-DOS was… well… the word “hidden” is too much; but there’s no question that Microsoft thought it could get away, with ME, with just pretending that DOS didn’t exist; that ME, alas, really was an operating system… and that was just bunk.

Only with the advent of NTFS-based Windows NT did Windows, itself, finally become a operating system, in its own right; and with that came that the command line only actually approximated — faked, in effect — the look and feel of the old FAT-based MS-DOS C:: prompt.

The easiest way to think of Windows 2000 was that it was nothing more than Windows NT, but with fancy-dancy Windows ME-like graphics and icons to spruce it up a bit. One thing Win2K had, though, that was REALLY nice, was a TCP/IP stack straight from Sun Microsystems… the only time Microsoft ever did anything like that, thereby making it the best one in any version of Windows, ever! Too bad Microsoft decided it didn’t want to pay Sun Microsystems a little tiny piece of every copy of Windows it sold, and went back to the glitchy-to-this-day Microsoft TCP/IP stack with all subsequent version. Ugh. The dark and dirty little secret of Windows 2000 was that Microsoft realized its mistake, and succumbed to its own greed, so soon after Win2K’s release that that, in reality, is why Win2K lasted so short a time. It was like a flash in the pan… here, today; gone, tomorrow. The truth is that it was originally SUPPOSED to be what XP ended-up being; but Microsoft killed it, in effect, so it could stop paying Sun and get XP out.

Microsoft basically rushed Vista onto and off the market, too, if you think about it; and one can argue that all of Vista’s service packs were really just to finally get Win7 where they wanted it so that THAT could become the new flagship to finally allow Microsoft to retire XP.

Truth be known, Windows XP was the first truly new and different version of Windows since Windows NT, and Windows 95 before it, and Windows 1.0 before that. In fact, those are the real “new and different” demarcation points…

1) Windows 1.0 (of which 2.0, 3.1 and 4.0 are family members)
2) Windows 95 (of which Win98 and WinME are family membes)
3) Windows NT (of which Win2K is a family member)
4) Windows XP (truly unique among Windows versions)

…followed, of course by Vista (of which Win7 is a family member… most, in fact, think of Win7 as little more than Vista, but finally fixed); and then, now, finally, Windows 8 and 8.1, which is an animal unto itself… unique, like WinXP.

And so the complete list of “new and different” demarcation points is:

1) Windows 1.0 (of which 2.0, 3.1 and 4.0 are family members)
2) Windows 95 (of which Win98 and WinME are family membes)
3) Windows NT (of which Win2K is a family member)
4) Windows XP (truly unique among Windows versions)
5) Windows Vista (of which Win7 is a family member)
6) Windows 8 (and its, in effect, service pack Win8.1)

That’s really the way to think of it.

All versions described it items “1)” and “2)” above are FAT, and/or FAT-16, and/or FAT-32 based; and all versions described in item “3)” and onward are NTFS-based.

Hope that helps!

Regarding Win8, I also beg to differ with “[t]he OS replaces the more traditional Microsoft Windows OS look and feel with a new “Modern Interface” consisting of flat tiles that first debuted in the Windows Phone 7 mobile operating system.”

That’s actually not exactly accurate. What’s accurate is that Win8 contains almost exactly the same basic interface as Win7, sans (more accurately, crippled by the absence of) the “Start” button (which button even Win8.1 didn’t completely properly replace).

However, what Win8 *ALSO* has, which no previous Windows version had, is an alternative interface — actually, the default interface… that is, until Win8.1 allowed the user to easily change it, and Win8 allowed the user to more difficultly change it — which caters to the world of touch screen (primarily mobile) devices like tablets and phones.

That’s really the truth of it. Saying it any other way is playing right into Microsoft’s classic manipulations of truth for purely marketing purposes… just as it did with ME; and just as it did with Win9x before it, whenever it tried to call them “operating systems,” when, in fact, MS-DOS was the operating system, and Win9x and ME were but graphical user interfaces (GUI) sitting atop.

It’s important that we give Microsoft its due; but it’s even MORE important that we call it — and its disciples — on it’s trying to pull the wool over our eyes. Remember that Microsoft is the same company which once insisted that the Internet’s Worldwide Web was just a passing fad, and so made no browser for it, leaving, initially, Netscape to be pretty much all there was at first; and then when Microsoft finally realized how desperately wrong it was, it came-out with Internet Explorer; but in its arrogance, thought that it could make-up its own Internet standards in it.

Microsoft has always been a bad-boy bully, and it’s important that that fact is never lost to history; and it’s eye-witnesses like me who are just the people to help us all never forget.

It’s one of being old’s few advantages.



Actually, Compuguru4u, they were 5.25-inches in size. But they were, indeed, “floppy”… the last disks (actually “diskettes”), in fact, that were truly “floppy.” The later 3. 5-inch ones were actually quite firm… at least on the outside.

Were you around to see the even LARGER truly floppy ones BEFORE the 5.25-inch ones; the ones commonly used in DEC and other machines? Yikes! I remember working for Automatic Data Processing (ADP) Dealer Services Division, and installing some of the first “factory communication systems” into GM dealerships using the old…



  which, as you can see, was almost bigger than today’s laser printers. Those are 8-inch floppy (truly floppy) diskette drives you see, there, with the red handles on the front.

Windows 2000 -> No visual effect, no non sense pure computing for work.
Windows XP -> 500MB, CD based installation had everything we needed, work play, what ever

Windows Vista / 7 -> almost 4gigs, still you can have both world of simple no non sense computing and work.

Windows 8 / 8.1 -> Man, its all play .why with 4 gigs of OS had to omit classic computing feels and looks ?? I mean with even 4 gigs of space, you cant keep the classic windows feel, basic start menu and all that??

Seriously, I find it easy now a days to teach Ubuntu compare to Windows 8 as Xp / or 7 had that classic Windows feel and was much easy to explain to new users compare to Windows 8..



Surely things are going more complicated and now a days for basic work and Internet, ubuntu feels easy
